- Speak with Urag gro-Shub.

- (Optional): Free Orthorn.
- Return the books.
Find Urag gro-Shub, who is probably in The Arcaneum. He will tell you none of the books in the library at the moment can help on the topic of the artifact found Under Saathal. However, he suspects that three books that have been removed from the library could help your research. The books were stolen by Orthorn, a former member of the College that has left to join a group of renegade mages in Fellglow Keep.
Travel to Fellglow Keep, and make your way through the Fellglow Keep Dungeons. In one of the holding cells you will find Orthorn, who will beg you to set him free. If you do, he will offer to come with you while you search for the books. As you progress further, you will find an unusual gem on a table in an upstairs room, to left of a door that is barred from the other side. You may encounter a Frost Atronach and several mages in the downstairs area.
Make your way through Fellglow Keep Dungeons, Fellglow Keep, and reach the Fellglow Keep Ritual Chamber, where the three books are found, guarded by The Caller. You may chose to trade the books for Orthorn, persuade The Caller to let you have the books, or fight her for them If you choose to fight, there are some elemental resistance potions and spell scrolls just outside the Ritual Chamber that may be helpful.
If you have an invisibility potion or spell, you can use it immediately following the conversation, before she conjures up her assistants, then attempt to remain undetected and kill her stealthily from behind. You could also agree to trade Orthorn for the books, then sneak up behind her and kill her. Alternatively, you can make yourself invisible when the conversation ends, then hide behind one of the bookstands in an alcove until everyone calms down. If you don't want to kill her, the book she is reading is the most difficult to get, as she is apt to notice you taking it. If taking this approach, you must also pick her pocket for the key to the exit door.
If your Speech capabilities are good enough, you may be able to convince The Caller that you will just take the books and leave, causing no further harm. If you are holding a grudge against her, this is an excellent time to sneak behind her and finish her off.
The books to be collected are: Night of Tears, The Last King of the Ayleids, and Fragment: On Artaeum.
Return the books to Urag gro-Shub to complete the quest and receive your reward.
