There is a pile of rubble to the left which yields Codex 248: Extra-Curricular Studies and a chest off to the right. Head around the circle and enter the first door on the left. Here a Desire Demon has a Templar bewitched. Interestingly enough if you choose to let them go Leliana approves. However, if you kill the demon the Bewitched Templar drops Templar Armor and Codex 244: Desire and Need . The book yields Codex 154: The Tevinter Imperium , the vanity and closet contain a gift. The other room on the left has more enemies and a Blood Mage. A Leghold Trap also sits in the doorway. The Blood Mage drops Archon Robes , there is a pile of books, chest, and closet to be looted though the chest requires high cunning to unlock.
Enter the middle room to meet a demon that throws you into the fade. You gain a new quest “ Lost in Dreams “.
