He was Blaine's character, and this appears to be day 2. I'm a little confused about this too, i.e. we have only one death and it's Blaine, who resigned, but the text implies the Anti-DFs killed him:

All the guests were shown to their rooms for the night, even the reluctant Bekkar. They were somewhat apprehensive when they found out their rooms didn't lock but eventually settled in for the night and to their own intrigues. A number of them had artifacts which they activated during the night.

While most of the guests were busy in their rooms, two figures sole through the hallway into a room that was not theirs. Silently they approached the figure who had fallen asleep in his bed.

"You make too much noise!" one hissed to the other. The other glared but let the first proceed. A carefully placed dagger-thrust was all it took. The man who was known as Revin died quietly.

One of the men jerked his head toward the pack full of papers and objects sitting on the table and the other shook his head, indicating the hall. They both slipped out, not bothering to close the door.

Morning dawned...

We don't really know anything about Revin/Blaine, other than he was stabbed to death, no 'he's vanilla' or 'loyal to the DO' etc. I also don't know why the Anti-DFs would kill him. Personally I'm still confused on how our lynch works, so maybe Kylia could clarify this OOC.
