You'll encounter several ghosts while in The Academy Library. One of them is Taryan Graye.
Talk to her if you wish to learn what happened at The Academy. She'll also tell you about her beloved Raedalus.
Unfortunately, the lovers cannot be together as Raedalus's spirit is in the locked section of the library. Reaching it will become possible only if you do the following steps:
- Step on the trapdoor in the middle of the hall;
- Press the button on the eastern wall;
- Activate the Unusal Tablet by the eastern wall;
- Pull the right lever by the door;
Enter the room and speak to Raedalus. You'll learn some further facts concerning the fall of The Academy. And don't forget to point him at Taryan.
Return to Taryan to complete the quest.
