Vengeance of a Burned Witch

From the publishers blurb:

A witch that had been burned returns. Her bones need to be recovered. A contract needs to be destroyed. An otherworldly ally of hers has to be faced. Where? How? Try to learn that from the panicking villagers. It is the only way to learn it. Vengeance of a Burned Witch is a one-session side-quest where talking to the NPC is vital for solving the adventure as a whole. It is not a big affair, and it has in-build set-backs to deliberately frustrate the players a bit. But in the end, success will be so much more sweeter for it. ...oh, did I mention that no riches and no impressive magical items are to be gained? And that it is yet not a “nega-dungeon”? Take my word on it.
