Nice to have a "small" Domain of Dread. While the previous one was clearly aimed at paragon, this one is heroic through and through. A single town beset by evil (and rotting from within), instead of a large city. I wonder if for an epic domain we'll have a whole nation, like in the Ravenloft setting? Maybe one of the old ones could be revived.
Interesting that one of the most potentially helpful NPCs is a priest of Asmodeus.
I find it kinda odd that the domain wit as created by what was really an accidental death, though his lack of remorse about it means Lord Graef probably would have done it anyway even if his son hadn't suffered Death By Falling Over. Perhaps it was the perfect storm of cowardice, manslaughter, remorselessness, and cruelty.
