He doesn't have a journal, no, or we'd all be screwed already. The only one from the same world as the Lord that has one that I know of is an ally against the Lord - he goes by Sil.

[Sil's written in the journals a few times, so if Darnell ever goes back over them, he'll eventually find something Sil's written]

How he takes a name, no one really knows. I assume it has something to do with his bloodline abilities. People from the world he's from have fae magic in their blood, and Leitner's line have some ability to manipulate memories. There was a night a few days ago where everyone either couldn't remember who they were, or thought they were a part of the castle's world.

What he does with those who's names he's taken varies. Those who can make things, he binds to him so they will continue making the things he wants, for example. Women he might bind for others reasons. [Sync is pretty sure he doesn't need to explain that, which is good, because he actually can't explain it well. His own knowledge on that sort of thing is severely lacking]

It all depends on how a person can be useful to him.
