Istredd plans on going into Sam's domain at some point to take down all the notes himself. He wants as consistent a record of everything that was said and done that he can get. He's a historian, he understands all too well about how badly reported on situations can lead to false facts in the future. Some day when they're gone, sent back or dead, there will probably be legends about this group of Summoned. He wants records somewhere. It's in his nature although they would disappear with him, so it's an imperfect system.

Well he's been neatly trapped, hasn't he? Istredd walked himself into this one after saying he wasn't sure about going. He is afraid of leaving this room let alone the castle, but he is much more anxious about Lucifer being somewhere else. He is clingy enough to need to sleep under his bed. Plus what if he is taken next? No, they have to stick together.

Blue eyes slant to the side for a moment as he considers, but when he does look back he lets Lucifer hold his gaze, reluctantly resolved. "Yes, fine. I'm fairly sure it's for the best I go as your compassion translator to the grieving family." It's an excuse for why he has to go. To help Lucifer, obviously, not because he is days away from becoming a shut-in with no end in sight.

Kyle told me about the private books they had here on High Magic and the gods. He recommended I ask Ambrose to see them. Despite the fact you don't like Lyle, it may be worth seeing if the area with Wild Magic may know more than this place. Ambrose may not like Lucifer, but he has reasons to like Istredd.
