Doru, the Blaspheme
This creature appears like a corpse surgically modified by a lunatic.
See the Boneclaw Guardian in Dungeon 157.
Doru is the hub of the necromantic infection. If the blaspheme is destroyed, all infected zombies immediately become lifeless corpses and fall where they stand. This immediately ends the zombie incursion. Other undead leave the village once the zombies cease.
