In the bowels of one of Westcrown's most esteemed noble halls lies an unparalleled evil, a terror that transcends reason and sanity, imprisoned and broken by the magic of a deceased archmage. For years this menace has been chained, all taken to test the bars of their own prison, gathering their hatred and planning revenge. Now, a conspiracy has weakened the chains that bind this nightmare, and as they shatter, the echo of the promise to consume all of Westcrown in hellfire is heard. Will the PCs be able to infiltrate the labyrinth of a madman to put an end to an evil more powerful than even the most legendary heroes? And who could want the downfall of Westcrown by placing it on the pot of a sacrilegious bet?
