Wolfskin's Curse

You stay the night in a walled town with your travelling companion. The master of the town has invited you and three others to partake in a banquet on All Hallows' Eve. But as the moon wanes, the scent of fresh blood can be smelled as a scream punctures the night. Your companion has been accused of murder: after all, he's beginning to take on a monstrous form, and the easiest option would be to blame him. The curse brings with it deceit. Can you prove his innocence to these strangers? You have until sundown.
