Mas and Zel, agents of Shond, are dispatched to Willowbrook, where something has gone wrong. Undead wander the area, attacking anything in their way. Demons raid the region at will, kidnapping and murdering. The undead were seen leaving the basement of a temple to Shond — which is either a coincidence or evidence that the temple has been corrupted by heresy. The two must find the source and stop it.
