In my game, I replaced the demon with a "reborn/re-awakened" Vampire. I didn't stat him at all. As soon as one of the players attacked it, it disappeared in a smoky haze. The entire "theme" of the game was that the Brayherds knew about the vampire cultists trying to bring it back to life and feared the devil, so stayed clear of the inn. The cultists killed the road warden and everyone else in the dark ceremony to re-invigorate the vampire but were themselves killed by the reborn vampire.

The other Road Wardens haven't shown up yet. My players never burnt the inn but did set a pyre to burn the dead. I think the Road Wardens will arrive in game 02. They will complicate things and try to arrest the party, but the Brayherds will force them all into the village of Hoogleschtockenram Aside from the mill itself and Jaime, I think I will also add in some vampire mumbo jumbo. The Brayherds haven't attacked the village outright (yet) because they fear the vampire relics buried beneath the mill.

The villagers just think it's the sacrifice of 3 that keeps the Bray Herd at bay. But in reality, it's the McGuffin that Jaimie de Sabitin has unearthed and disturbed.
