The Vulgar Unicorn is the black heart of Sanctuary's corruption. When something bad goes down in Thieves' World, it always seems to start in this rundown dive. In this gripping adventure, what seems like just another murder leads to the unmasking of a terrible conspiracy involving Dyareelan cultists, Nisibisi refugees, and a dangerous plague that could destroy the city. Murder at the Vulgar Unicorn is the perfect starting point for a Thieves' World campaign. In addition to the adventure proper, the book also provides full details and maps of the most infamous bar in Sanctuary: the Vulgar Unicorn itself.
