The Daedric quests are unrelated to one another but correspond to the 17 Daedras in the game (although if you played the Shivering Isles expansion in Oblivion, it would explain why there are only 16 quests).
AZURA: THE BLACK STAR
You first hear whispers about the Shrine of Azura by asking the barkeep at the Bannered Mare, at which point you are given this miscellaneous task to visit it. Make the trek to Shrine of Azura, located south of Winterhold, and speak to Aranea Ienith to begin this quest.
Note that this quest can also be gained from wandering followers on pilgrimage to the shrine. They'll mark it on your map for you if you ask them.
Find the elven mage from Aranea's vision
Speak to Nelacar
Find Azura's Star
Bring the Star to Aranea or bring the Star to Nelacar
Tell Azura you're ready to enter the Star
Tell Nelacar you're ready to enter the Star
Destroy Malyn Varen's soul
Speak to the innkeeper at the Frozen Hearth in Winterhold and ask about the elven mage that studies stars. He will tell you where a wizard named Nelacar staying at the inn. Nelacar has severed all ties with the College, but you can placate him with a good Speech check or bribe him.
After hearing his story, you will need to seek out Maylyne in Ilinalta's Deep, southwest of Whiterun. This place is filled with powerful necromancers. There are also two Skill Books in here that will level up Enchanting and Conjuration - don't miss them! At the end, you will find the broken Azura's Star.
The quest now has two conclusions: A communion with Azura or a chat with an old elf. You get the Azura's Star and a pretty strong mage follower if you decide to deliver the star to Azura. You get the Black Star if you decide that you want to side with Nelacar.
A COMMUNION WITH AZURA
You can journey back to the Shrine of Azura and speak with Aranea (the npc that will become a follower if you decide to go this route instead of the other). When the Star is placed upon the alter of Azura, she tells you that without Malyn Varen's soul being purged from the star, it is utterly useless. Azura offers to teleport you into the Star to deal with him yourself to finally purge his soul from the Star.
CHAT WITH AN OLD ELF ENCHANTER
You can journey back to the Frozen Hearth Inn and speak to Nelacar as well. After Nelacar looks at the Star, he discovers that Malyn Varen's soul is trapped inside. He tells you that he can repair the star, transforming it into a vessel that stores black souls. (black souls refers to human souls (From townsfolk, the forsworn, or bandits) that can't be ordinarily stored in standard soul gems. These are used for Enchanting purposes) Malyn must be purged from the star and thus you must be soul trapped into the star to deal with him.
NO MATTER WHICH YOU CHOSE, YOU ARE SENT INTO THE STAR TO DEAL WITH MALYN
After telling Malyn that he cannot escape his fate, run after him. He will summon up to three Dremora and shoot pretty strong lightning bolt attacks from his staff. Quickly nullify the enemies, and then strike down Malyn. After you win the fight you are transported back to Skyrim.
Malyn's soul has been sent to oblivion. You are now ready to recieve an offering from whichever side that you chose before entering the star. In addition, if you are at the shrine of Azura, you may speak with Aranea Lenith again. WIth her guardianship at an end, she offers to accompany you as a follower, if you'll agree to it.
OPTIONAL: If you aren't of high level, are having difficulty disposing of the dremora, or don't need the extra daedra hearts. Exit out of dialogue while Malyn is speaking, run up to him and kill him quickly. Use slow time if needed. Then just avoid the dremora until Azura teleports you out!
The person (Nelacar or Aranea) you did not side with has some harsh words with you, if you meet up with them again. Aranea obviously will not become your follower if you side with Nelacar...
You'll find Boethiah's Calling by reading a book named Boethiah's Proving or encounter a Boethiah follower. If you encounter and kill a Boethiah follower, you will receive a miscellaneous objective to "Investigate Boethiah Cultist". Search the cultist and take the book off him. This completes the miscellaneous objective. Read the book to launch the quest.
There is a prerequisite of level 30 or higher before you can take on this quest.
Find the shrine of Boethiah
Find the cult of Boethiah
Lead someone to become trapped by the shrine and slay them
Speak to Boethiah's Conduit
Slay the other cultists
Slay everyone at Knifepoint Ridge
Retrieve and equip the Ebony Mail
You can find the shrine to Boethiah at the Sacellum of Boethiah east of Windhelm and north-northeast of Narzulbur. You can only receive this quest once you reach level 30, so level up if you haven't already or you will NOT receive the quest upon arriving. If you are level 30, simply discovering the shrine will give you the quest. You will then be prompted to find the Cult of Boethiah.
They aren't far off. Follow your quest marker to the cult and a priestess will approach you, give you a Blade of Sacrifice, and tell you that you must bring a follower to the Pillar, activate it with them in the vicinity, and slay them on the pillar. You're probably not too keen on killing any of your followers that you've gained in your adventures, so it may be best to grab a Hireling to do the dying. Hire one for 500 gold and bring him to the pillar. Place him near it,(you have to order him to touch pillar) activate it, and once he becomes attached, do the deed. Boethiah will possess your now-deceased follower and give you further instruction (if you have also completed the main Dark Brotherhood quest line, you can just use one of the initiates, they don't cost a singe septim). Also, if you just kill the apostles, she will take over one of their body'S and proceed with the quest. (If you choose this route, I advise having Ice form.)
Next you're gonna have to kill every one of Boethiah's apostles, and there's a decent amount of them. Stay back and let them duke it out, then come back in to clean up the rest. Once that's done, Boethiah will appear again and instruct you to take down her previous Champion, take his Ebony Mail, and kill the rest of his bandit companions. You don't actually have to kill them stealthily; killing them the old-fashioned way will suffice. Head to Knifepoint Ridge and take them out, and retrieve the mail. Boethiah will contact you one last time once you equip it, and congratulates you. She gives a brief speech and then allows you to keep the armour, which envelopes you in a poison shroud during battle which damages nearby enemies, and also enhances your sneaking abilities. Plus it has a high armour rating. Sweet.
A DEADRA'S BEST FRIEND
A Daedra's Best Friend is part of the 15 Daedric Quests in the game. This one concerns Clavicus Vile and can be initiated by visiting Falkreath. You must be at least level 10 to activate this quest.
Travel with the dog Barbas to the shrine of Clavicus Vile
Retrieve the Rueful Axe with Barbas
Return to the shrine of Clavicus Vile with Barbas and the Rueful Axe
Give the Rueful Axe to Clavicus Vile or Kill Barbas with the Rueful Axe
Never retrieve and return the Rueful Axe and keep Barbas as a follower
Travel to Falkreath and find Lod, he will tell you about an annoying dog and that you should take care of it. You can find the dog near The Dark Brotherhood Sanctuary. To your utter surprise, the dog speaks to you! It tells you its name is Barbas and that he needs your help. Start the quest and either follow the dog or just go to Haemar's Shame which is due east of Helgen (which is east of Falkreath).
Inside the cave there are many vampires (beware, as you could catch Vampirism). Vampires are particularly susceptible to fire and highly resistant to frost. Talk to Clavicus Vile's statue and he will send you on a quest to get the Rueful Axe. Travel to the Rimerock Burrow and retrieve the axe. You can keep it now and never turn it in and take advantage of the exploit (see the following) or do this:
When you return to Clavicus he will give you two options: 1. Kill the dog and keep the axe, or 2. Insist on returning the axe and he will reward you with Masque of Clavicus Vile (upgrades speech by 10 points, and changes prices to your favour by 20%).
Warning - Don't kill the dog if you wish to get the Oblivion Walker Achievement/Trophy
DISCERNING THE TRANSMUNDANE
Discerning the Transmundane is a Side Quest in TESV: Skyrim. It is acquired from Hermaeus Mora, and will take players through a series of dungeons and puzzles to find an Elder Scroll.
It is one of the Daedric Quests available in the game and can be initiated during the quest Elder Knowledge, in which you retrieve the Elder Scroll from the ancient dwarven city after you talk to the College of Winterhold librarian.
Note that you must be level 15 or above to finish the rest of this quest.
Ask Urag about the insane book
Find Septimus Signus
Transcribe the Lexicon
Give the Lexicon to Septimus
Harvest Falmer blood
Harvest High Elf blood
Harvest Wood Elf blood
Harvest Dark Elf blood
Harvest Orc blood
Bring blood to Septimus
Take the Oghma Infinium
Urag in the College of Winterhold starts this quest. Read the book, then speak to him to be sent on a quest to locate Septimus in an isolated area north of the College. There is a path leading down and across various icebergs. Once you've spoken to the loopy old man, you will need to start heading to some Dwemer ruins.
The inside of the ruins is rife with traps and mechanical enemies: Dwarven Spiders and Dwarven Spheres, to be exact. If you ever get lost navigating this huge area, just remember that the idea is to head deeper into the subterranean level, where you eventually come upon Falmer enemies that can poison you.
When you reach a gated area with seemingly no lever in immediate sight, you need to head behind and up the stairs to the altar overlooking the gate to unlock it. There, interact with the Dwarven mechanism to open another way through to Blackreach. Meander through Blackreach to fight off some more Falmer and a Dwarven Centurion, going deeper yet to a lift that takes you to the Tower of Mzark.
It is there that you finally place the Lexicon into the slot next to the beacon for the huge mechanism in the room. Press the left button of the two available until the a third button lights up on the left. Press that until the last button lights up, then take the Runed Lexicon from the slot.
Head back to Septimus Sigmus now, using an elevator short-cut in Blackreach. The quest continues if you are level 15 or above; if not, grind your way up and wait for a courier to deliver a message, prompting you to return to Septimus.
The next thing Septimus requires -- it's not much -- is just the blood from each of the following: Wood Elf, High Elf, Dark Elf, Orc, and Falmer. You can harvest blood from the deceased. A good location for acquiring all except the High Elf blood is Liar's Retreat, southwest of Dragon Bridge and Chillwind Depths.
For High Elf blood, you can simply go to the Thalmor Embassy and kill a Justicar.
When you return, Hermaeus Mora will dispose of Septimus and allow you to take the Oghma Infinium. This unique item will grant you 3 levels and 5 skill points to each of the following:
Combat: Smithing, Two-Handed, One-Handed, Blocking, Heavy Armor, Archery
Stealth:Alchemy, Sneaking, Pickpocketing, Lockpicking, Speech, Light Armor
Magic: Enchanting, Destruction, Illusion, Conjuration, Alteration, Restoration.
ILL MET BY MOONLIGHT
Ill Met By Moonlight can be started in Falkreath and is one of two quest paths towards becoming a Werewolf. It is part of the Daedric Quests.
To start the quest speak to Mathies in the Falkreath graveyard. The graveyard is to the North, between the wall surrounding the city and the first building, as you walk into Falkreath after traveling.
If you killed Mathies, or if a dragon managed to, simply go into the Falkreath Dungeon below the Guard barracks and speak to Sinding to start the quest.
Speak to Sinding
Kill the great beast
Begin the hunt
Hunt or Spare Sinding
Speak to Hircine
Kill the Hunters
Talk to Sinding
For maximum benefit become a werewolf before starting this quest. This way you can have unlimited werewolf transformations.
In Falkreath, a man named Mathies has just lost his darling little girl to a serial killer. You can start the quest by prying a little into his personal life and asking about who died. This will lead you to the murder in jail
Sinding is the man in prison for murdering a girl. Talk to him and he'll tell you his story. After the story, he'll give you an unequipable cursed ring. He will then transform into a wolf and escape jail. Your next objective is to return the ring.
After tracking down and killing Hircine's Beast (don't freak out, it's just a stag) Hircine will speak to you through the stag's spirit. He will tell you to hunt down Sinding. Accept the hunt and track him down to Bloated Man's Grotto.
Enter the Grotto and talk with Sinding. This is where the quest splits up and gives you different rewards for the outcome. Either follow those rules, or try a third option (Seems like a glitch) and receive both.
Don't kill Sinding. Instead, help him kill the hunters. Hircine will tell you to kill Sinding. Now exit and Hircine will appear again in his stag glory to ask you if you killed Sinding. It doesn't matter if you pick "I failed" or "I disobeyed your orders" he will still commemorate you about turning the hunt around (hunters become the hunted). He will then take the Cursed Ring of Hircine and uncurse it, providing you with the Ring of Hircine. The ring only works if you're already a Werewolf!
Kill Sinding. Skin his body, and Hircine will appear on sight to turn Sinding's skin into Savior's Hide, a magnificent Light Armor that is one of the best in the game. For max effect, smithing it improves the quality drastically.
Do not kill Sinding. Help him kill the Hunters, exit the cave, Hircine will greet you, quickly exit the conversation if Sinding has exited the grotto with you, kill and skin Sinding and another spirit of Hircine will greet you rewarding you with the Savior's Hide. After this talk to the other spirit of Hircine and he will reward you with the Ring of Hircine. If Sinding doesn't exit the grotto, receive your reward for killing the hunters, go back into the grotto kill and skin Sinding, leave the grotto and you will be rewarded.
THE CURSED TRIBE
The Cursed Tribe requires a minimum level of 9 to initiate. It is part of the Daedric Quests.
Bring Troll Fat and a Daedra Heart to Atub
Observe Atub's ritual
Speak with Yamarz
Meet Yamarz at Fallowstone Cave
Defeat the Giant
Take Shagrol's Warhammer back to Largashbur
Place Shagrol's Warhammer on the shrine in Largashbur
Go to Largashbur (south of Riften against the mountain-line) and Atub will tell you how the giants keep attacking their outpost and their leader is sick. Bring her a Daedra Heart and Troll Fat.
Travel North East of Riften with the Orc leader and fight your way until you get a proposition: tell the orc to get the mace from the Giant himself, or let him bribe you. If you make the orc kill the giant he will ultimately fail and you will have to slay the giant. If you accept the bribe, you must kill the giant and bring the mace back to the orc leader where he will turn on you (trust issues obviously).
When you return talk to Atub and Malacath will instruct you to place the mace on the altar. When he is done talking the mace will be transformed into Volendrung (2h mace) that you can take off the Altar.
Note that some players have had difficulty entering the Largashbur compound if Ugor, who would otherwise unlock the front gate, dies during the initial approach to the fortress. However, approaching any other Orc fortress such as Dushnikh Yal just southeast of Markarth will open up a miscellaneous objective to retrieve a set of Orcish gloves called The Forgemaster's Fingers. Once returned to the quest-giver, you will be named Blood Kin of the Orc tribes and have access to any of the Orc fortresses across the map.
PIECES OF THE PAST
Pieces of the Past cannot be attempted until you reach at least level 20. Once you do, you'll receive an invitation via a courier upon reaching any city in Skyrim. This prompts a Miscellaneous mini-quest to further investigate.
Speak to Silus inside his house
Retrieve the pommel of Mehrunes' Razor
Retrieve the blade shards of Mehrunes' Razor
Retrieve the hilt of Mehrunes' Razor
Bring the pommel stone to Silus
Bring the blade shards to Silus
Bring the hilt to Silus
Meet Silus at the Shrine of Mehrunes Dagon
Speak to Mehrunes Dagon
Reforge Mehrunes' Razor
Claim Mehrunes' Razor
To start the mission of acquiring Mehrunes' Razor, you need to go speak with a member of the Mythic Dawn, named Silus Vesuius. There is a mythic dawn museum in Dawnstar and he will be standing outside in front of the museum. Go and talk to him and then he will instruct you to find the pieces of the razor.
The shards are located in the trap-laden vault of Cracked Tusk Keep. The vault is locked so you may want to hunt to resident bandit chief, Ghunzul and loot the key from his body.
For the Hilt, head to Morthal and talk to Jorgen. He works by the sawmill. A high speech skill makes this part of the quest extremely easy. If you managed to convince him, he'll give you the key to his house and chest. If you don't want to waste time talking to him, you can just pick the locks of the door and grab the hilt from the chest inside.
The pommel is located in Dead Crone Rock. Be careful as you approach this area, as there are a lot of enemies patrolling the area (forsworn, etc.) You need to enter the building first then exit to Skyrim again to reach the upper level where a hagraven and Word Wall is found. Be careful of the soul gem-powered fire traps. Kill the hagraven named Drascua and deactivate the traps. Loot the pommel from Drascua's corpse.
Once the pieces are collected and you have spoken to Mehrunes Dagon. Kill Silus, careful though because he like to run and summon a familiar. Once he is dead Mehrunes Dagon will speak to you and then reforge the Mehrunes' Razor. Once you have claimed the dagger watch out as Mehrunes Dagon will summon two very nasty Dremora whom will attack you. You can run or stay and fight. They can be equipped with fire enchanted weapons, so keep that in mind when fighting them. Once dead they will have a key each to Mehrunes Dagons shrine and don't forget their Daedra hearts (which can be sold for a pretty penny or used for making Daedric armour).In the shrine , you can fight two more Dremora . The shrine has a good number of loot, including several gold ingots. The weapon drops for the Dremora - ironically - can include a bow or weapon enchanted with the Banish enchantment, which is very useful to make money in the game.
Magical ability: Hits have a small chance to instantly kill. If smithing skill upgraded in improving magical weapons/armour, Mehrunes’ Razor Damage rating will be 50. Damage can be even higher if you use fortify potions, enchanted amulets, rings, and clothing that will improve weapons and armour and if One-handed weapon skill is very high. Needs an Ebony ingot to upgrade.
THE WHISPERING DOOR
The quest The Whispering Door isn't available until your character is level 20 or higher. You must also have completed Dragon Rising. You can get this quest by first gathering rumors from the barkeep at the Bannered Mare in Whiterun and then asking the Jarl about his children.
Find out what's wrong with Nelkir
Listen to the whispering door
Speak to Nelkir
Obtain the key to the whispering door
Open the whispering door
Retrieve the Ebony Blade
Talk to the innkeeper of the Bannered Mare in Whiterun and ask her about the latest gossip in town. Afterwords a quest will appear telling you to Ask Jarl Balgruuf the Greater about his children, in which the Jarl is located at Solitude. Furthure more you will need to talk to Nelkir, located in Whiterun, Go to the door in the basement and attempt to unlock it. The Whispering Lady will then begin to speak to you. She tells you that the dark child (Nelkir) will guide you. Find and speak to Nelkir again, and he tells you that the only two people who can open the door are Balgruuf and Farengar. Acquire the key from the Jarl Balgruuf the Greater or Farengar Secret-Fire by pick-pocketing him. Once you obtain the key, go back to the basement and open the door. Enter the room and retrieve the Ebony Blade. The Whispering Lady will speak to you again once you take the blade. This blade isn't charged by soul gems, however. It Absorbs the life essence of your foes and is strengthened by the blood of deceit. (It was an old piece of script, scrapped, but it was originally scripted so that the children would commit patricide, and if you don't know what that is, it's the murder of a father)
THE BREAK OF DAWN
You need to be level 12 or higher before you can attempt The Break of Dawn. You must also collect Meridia's Beacon (this can be found in the cave in "Ill met by Moonlight", but it isn't the only place). You can start this quest by visiting the statue of Meridia.
Bring Meridia's beacon to Mount Kilkreath
Replace the beacon
Guide Meridia's Light through the temple
The statue of Meridia is located near the Mountain Range west of Solitude.
Go to the temple and activate the pedestals of light that unlock the doors. Along the way you will have to fight corrupted shades. At the end you have to fight the necromancer Malkoran and kill him. Once he dies, he becomes a shade that you must defeat. After activating the final pedestal of light, you are teleported back to Meridia, who gives you the sword called Dawnbreaker.
Tip: Many "Descecrated corpses" can be found during this quest. Each of this corpses contains 20-125 gold. Looting every one of them will give a great amount of gold.
Tip:After you have defeated Malkoran, don't take Dawnbreaker from his pedistal just yet. There are many 'Descecrated corpses' lying around with a lot of money on them. Loot them before you take Dawnbreaker, as you will not be able to enter this room again, after you are teleported out.
THE HOUSE OF HORRORS
Search the Abandoned House
Find your reward
Find the priest of Boethiah
Go to the abandoned house
Beat Logrolf into submission
Speak to Molag Bal
This quest begins outside the Abandoned House in Markarth. Vigilant Tyranus, a vigilant of Stendarr, will ask if you know anything about the house. Offer to help and the quest begins. After a small conversation, you will be locked in the house with Tyranus and a voice will tell you to kill each other. Tyranus panics and attacks you, after you slay him the voice will tell you to go further into the house for your reward.
After going to the basement of the house, you will find a rusty mace that when activated triggers a trap that locks you in place. The voice reveals himself to be Molag Bal and the mace is his weapon that has been desecrated by a priest of Boethiah. Molag Bal orders you to find the priest and bring him to the shrine so he can make the priest submit.
The priest is in Bruca's Leap Redoubt, northeast of Markarth. You can find the priest, Logrolf the Willful on the northeastern edge of the camp. Talk to him and choose any conversation option to free him. Head back to the abandoned house.
Upon returning to the house, head to Molag Bal's altar and you'll find Logrolf trapped in the same way you were earlier. After some banter, Molag Bal tells you to beat Logrolf into submission with his Rusty Mace. The mace is automatically equipped so just pull it out and attack him.
You must reduce his health to zero twice to make him submit (Molag Bal revives him after the first time). After he submits, Molag Bal will tell you to kill him. Do this to receive The Mace of Molag Bal.
THE TASTE OF DEATH
To start this quest, speak to Brother Verulus. You can find him in Understone Keep, blocking a door to the Hall of the Dead. Talk to him about the Hall of the Dead and offer assistance. He will give you a key and tell you to investigate.
In or near the Halls of the Dead in Markarth, Eola will ask you to meet up with her at Reachcliff Cave, starting The Taste of Death. The location is south west of Markarth. Here you have two options
1) Enter the Cave alone
2) Ask Eola to accompany you
If you're a lower level (Less than 20) player it's better to ask her to tag along. The path is linear and there are a couple of Draugrs on the way. The final level has a high level Draugr Death Overlord who uses Shouts.
If you're a high level (over 40) the Draugr Death Overlord will be replaced by a nameless Dragon Priest. He will be powerful, but he does not carry one of the collectible masks.
Speak with Eola after the Cave is cleared. She will task you with finding a feast to please Namira. She needs a priest and wants you to convince Brother Verulus (He can be found at the Halls of the Dead in Markarth) to join you to the Cave.
Once you bring him to the cave, Eola will hypnotize him and make him take a nap on the altar of Namira. She proceeds to request that you kill him and take the first bite.
Afterwards, Namira will speak to you (but only if you eat) and reward you with The Ring of Namira. The ring increases stamina by 50 and will give you increase in health and health regeneration if you feed on a corpse (ring must be equipped to feed on a body, and a small menu will appear asking if you want to eat or search the body).
Warning It is possible to kill Eola after you begin the quest and if you do so, the quest will automatically fail and you won't be able to repeat it afterwards.
THE ONLY CURE
Obtain a Flawless Ruby
Obtain a Silver Ingot
Obtain a Deathbell Flower
Obtain some Vampire Dust
Deliver the ingredients
Inhale the fumes
Travel to Shrine to Peryite. Talk to Kesh the Clean and he will tell you to bring him the following items:
Silver Ingot (Blacksmith Vendor), Vampire Dust (Haemar's Shame has lots of Vampires, or go to an alchemist vendor), Flawless Ruby, Deathbell Flower (alchemist vendor). Deliver the ingredients to Kesh and inhale the fumes when ready.
When you are done communing with Peyrite, travel west to Bthardamz and clear out the dungeon. After killing the Orchendor, head back to the shrine. Activate the urn and the Daedric god will speak to you. After he has spoken, you'll obtain the Spellbreaker shield as a reward. You might remember it from Oblivion.
A NIGHT TO REMEMBER
YOU MUST BE LEVEL 14 (the quest won't start otherwise).
Go to a tavern in any of the holds in Skyrim . Speak to the man in the black robe (Sam Guevenne) and he'll ask if you want to enter a drinking contest with him. Accept it, and you will begin to drink until you pass out.
When you awake, you will find yourself in Markarth, in the temple of Dibella. The priestess will tell you came in, shouting, knocked stuff over and and passed out. She tells you to clean up the temple. Proceed to pick up the items located on your map.
After you are done, she will tell you the location of where Sam may be. Rather than picking up your mess, you can also try to persuade her to tell you - before doing this you might want to walk over the shrine and receive the Blessing of Dibella, which is Fortify Persuasion. A third option is to pay her off - do this and you can skip picking up your mess.
Go to the location she gives you and you will meet a farmer. The farmer tells you that you stole his prized goat and sold it to a giant. You can either find the goat, pay for it (1000 gold), or pass a speech or intimidate challenge. If you find the goat, you will have to first kill the giant you sold it to, and then slowly move back to Rorikstead so the goat will follow you.
Whichever you choose, he will tell you the next location to go - to Ysolda in Whiterun. You will approach a woman there. She talks about having a wedding ring for you after you told her how you met the love of your life and that you asked her to get you a ring. You can either Persuade, Intimidate or give her the money for it (2000 gold).
If you travel to the Witchmist Grove, you'll find your betrothed - a Hagraven. Talk to her and you have one dialogue option: To have the ring back. She will become hostile and start attacking you. Be wary as Hagravens are very formidible opponents. Once you kill her, loot the wedding ring off of her and return the ring. The woman will tell you the next location to go.
Whether you convince Ysolda or get the ring, she mentions that the wedding is at a place called Morvunskar. When you arrive, you will need to fight your way through a fort full of mages, so be prepared with magic resist potions or apparel. Fight your way through until you reach a magical portal located at the top of a set of very conspicous stairs.
Go through and keep walking until you find Sam. After some friendly banter, he reveals himself to be Sanguine, the daedric prince of debauchery, and gives the player his staff, The Sanguine Rose, for a fun time with the player when they were drunk. He teleports you out of the grove and that's the end of the quest.
Yet another reason why you will never go drinking with a daedric prince.
Note: Upon finishing the quest if you return to the Misty Grove, there is NO way to exit and you will have to restart from a previous save.
Note: If you fast travel to Anga's Mill Northwest of Morvunskar, a dragon will most likely be waiting.
THE MIND OF MADNESS
The quest, The Mind Of Madness, begins when you speak to Dervenin in Solitude.
When in the city of Solitude, a servant will ask you to help him find his master who is stuck in an abandoned corridor of the Blue Palace.
To gain access you can either ask one of the maids and tell her that Falk told you to clean up the area and she will give you the key; or, if Falk likes you enough (after you complete Wolfskull Cave quest), then Falk will give you the key.
When you enter, go to the second floor, walk down the hallway and you will automatically be transported to Pelagius' mind.(There have been reports of the game freezing before entering Pelagius' mind .SAVE.)
Speak with Sheogorath and you will get the Wabbajack. There are 3 steps to complete before leaving.
Paranoia (to your left) , this leads to an arena where 2 creatures will be fighting below you, fire the Wabbajack across the arena at the figures sitting on either side of the man, they will turn to wolves and attack him completing this scene.
Anger (to your right) , Use the Wabbajack on the figure "confidence" to make him big and the attacker smaller, you may have to hit him twice in a row to get him to the largest size and win.
Night Terrors (right down the middle) , here you come to a clearing where Pelagius is asleep in a bed, you must wake him. To do this fire the Wabbajack at him, then a wolf will appear, shoot the wolf and it turns to a sheep, then shoot Pelagius again. Repeat this as different enemies appear, until he awakens. "Friendly" characters will also appear, such as a young Pelagius and a Sultry Maiden. They do not need to be shot with the Wabbajack.
Once you have completed all three tasks to treat Pelagius's mind return to the glade where Sheogarath is seated at the table and speak with him. After some scenes he will return you to the Blue Palace and give you the Wabbajack. You find out that the God of Madness is the servant's master, and he returns to his home in . Be sure to continue down to the cellar to obtain the book the "Surfeit of Thieves" before leaving.
The Wabbajack, causes random things to happen when used, such as turning an enemy into a chicken.
To start Waking Nightmare talk to the priest Erandur inside Windpeak Inn in Dawnstar. After a bit of conversation, you will follow him up to the top of a nearby mountain, where you will battle some spiders. After that, you will talk to Erandur again. Then, you follow him into Nightcaller Temple.
As you walk through the temple, mages and orcs will wake up as you approach them, and subsequently attack you. After a bit of exploring, you will search for a book that allows Erandur to conclude that you need to search for a potion that enables you to live through another person's memory.
After drinking the potion and walking down a few hallways within the "dream", your character will exit the dream and rematerialise on the other side of the barrier that blocked you earlier. Once you activate a trigger to take it down, you will progress deeper into the temple. Once you get close to the skull, you will encounter two of Erandur's old companions. Once you kill them, Erandur starts a ritual to destroy the skull. You now have a choice:
Option 1: Let him finish the ritual and let the skull be destroyed. Erandur will become available as a companion. WARNING: Choosing this option will not count toward the required 15 Deadric Artefacts needed for the Oblivion Walker trophy/achievement.
Option 2: Kill him during the ritual and take the skull for yourself.
