 Fellglow Keep Dungeons
The entry leads into a narrow passage that has suffered quite a lot of damage, with fallen stones blocking part of a short flight of stairs leading down to the east. There is a dresser and barrel on your immediate left with a common book and an iron dagger on top, while on your right is a bucket containing two samples of scaly pholiota fungus. There are numerous barrels and sacks containing ingredients and food throughout the dungeon and keep. At the bottom of the stairs there is an iron battleaxe on the ground. The passage enters a small room that is partially flooded, where a Nordic barnacle is growing on some masonry on the ground, while amongst some rubble on the right is an iron mace. The passage continues to the southwest, through an open door. There is a bear trap in front of the door with a second trap a short way along the next passage. Ahead is another partially flooded room, this one has a balcony to the left where an ice mage is standing on guard with two frostbite spiders. There are two more Nordic barnacles and three slaughterfish egg clusters in this room as well as at least four salmon swimming in the flood water. There are many crates and unusable barrels around the room, on the balcony and throughout the dungeon and keep, with many items of clutter among them. There are stairs along the rear wall leading up to the balcony. In the southern corner is a long wooden table with a goat hide, bottle of ale, portion of grilled leeks, and an iron dagger on top. Behind the table, among thick cobwebs is a blue butterfly wing, while beside it is a counter with two petty and a random empty soul gems and common book on top. In front of the counter is a pair of iron boots and a basket containing a leg of goat. Against the northeast wall is a set of shelves holding a potion of healing, a potion of minor magicka, five common books, a leather strip, three bottles of alto wine and four bottles of wine. To the left is a small square table with two more common books and a random pair of gauntlets on top, while to the right of the shelves are two pieces of firewood.
To the southeast is a passage leading down a few steps to a T-junction with a pressure plate on the ground. This triggers a poison dart trap from the right.

Beyond this is a food barrel with a flute on top by an open door that leads into a larger room with four cells along the far wall. To the right of the door is a torture rack and hanging from the ceiling is a small cage. There is a mage around the corner to the right. Three of the cells have captive leveled vampires locked in them. You can either kill each of the vampires with ranged magic or a bow, or if you unlock the cells they will rush through the door to the southeast and attack a group of mages that have been performing dissections on a pair of master vampires, a Khajiit and Nord. The vampires will then leave the dungeon without attacking you (unless you attack them first). The cells are all apprentice locked and can either be lockpicked or on the southeast wall, to the right of a wooden door are four levers that each open one of the cells. The vampires may be carrying useful items including potions. There is a steel warhammer leaning against the wall by the rack. Under the levers is a dresser with a set of clothes and a hat on top.

 Fellglow Keep Ritual Chamber
The door opens into the Ritual Chamber, where you will finally find The Caller. Regardless of whether you are sneaking you will be instantly spotted and she will initiate a conversation. She is the leader of the group of renegade mages, and is quite upset over your presence and the destruction you have caused. She also possesses the three books that you require for the Hitting the Books quest that are located within this room. The books you seek are on three plinths, one in the center of the room and two in the center of alcoves behind.
Your options are essentially:
- Fight The Caller: either through certain dialogue options, by attacking her, or by picking up one of the quest books;
- Trade the books for Orthorn: through some dialogue options, The Caller will offer the books in exchange for your companion; if you accept, Orthorn will walk back to the keep, while you may pick up the books and leave without a fight. If Orthorn is not with you, and you tell her "Maybe we can come to an arrangement," she replies that you have nothing she is interested in.
- Persuade her to give you the books: She will then let you pick up the books without fighting;
- If you successfully persuade The Caller, Orthorn will act as if you accepted The Caller's trade, saying "How could you leave me here?" and walking off into the keep.
She will raise a Frost Thrall to aid in fighting you and will teleport each time you close with her and deal damage, have a follower or raising your own atronach can greatly help in the battle. Once she is dealt with collect the books Fragment: On Artaeum, The Last King of the Ayleids and Night of Tears. The Caller carries a Fellglow Ritual Chamber Key that opens a door to the northwest where you will find a boss level chest with a random shield leaning against it, a cupboard to the left holding a random helmet, a bowl hiding a bowl of bone meal, a bulb of garlic, a satchel, five soul gem fragments, a random filled soul gem, a copy of The Wolf Queen, v8, a random potion of healing, and a random potion. Beside the cupboard is a soul gem stand holding a random empty soul gem. To the right of the chest are two barrels of ingredients and beside them is a stack of crates with a sheaf of wheat, a medium coin purse and a gourd on top. There are a couple of food sacks among some rubble on the left and a trapdoor that opens a room in Fellglow Keep. The room has a door that is barred from this side. Through this is the two leveled rooms seen previously. The door opposite leads outside via the main door that was previously locked.
If Orthorn helped you, after the fight, Orthorn may tell you he will stay away from the College for a while, and leave you.
- The room across from The Caller can't be opened unless you have the Fellglow Ritual Chamber Key. This key can't be pickpocketed and can only be obtained by killing The Caller or by using the Wax Key perk on the vampires' cells in Fellglow Keep Dungeons. However, the door bar after exiting through the trapdoor can be lifted from the opposite side, enabling access to the treasure room before even meeting The Caller.
- As soon as you turn in the quest Hitting the Books, the upper part of the castle will be blocked, and more enemies will have spawned. If entered through the main entrance to Fellglow Keep (after you obtained the key) you end up directly in the living quarters. Right up the stairs there is the room to the right where some smithing equipment and an enchanter is found. The other two passages to the upper part of the castle are blocked by collapsed ceilings.
- You cannot clear this location during Hitting the Books since the boss is disabled for the duration of the quest.
- If you clear out Fellglow Keep before you accept the quest Hitting the Books, during the quest the game will crash when trying to enter the dungeon.
- To avoid this, enter
