Under The Devil’s Thumb
The city is plagued by an affliction being called "stone sickness" or "the gorgon’s touch" that disorients people and turns them to stone. Those with, or suspected to have, the affliction are being banished from the city. Some demand a cure, but most are just scared for their loved ones.
A ravenfolk woman named Spinel Larkdon, mother to a child with the gorgon’s touch, begs the PCs for assistance. An artifact known as the Shroud of Tiberesh, capable of curing any sickness, is locked away within The Umbers' vault of spoils below the city. Passionate, she is determined to save her son and all those afflicted.
Fortunately for the player characters, completing the Umber’s Gauntlet alive means they are not only entitled entrance into the cult, but also a single item from its vault of spoils. The PC's only hope of procuring the Shroud is by traversing this initiation Gauntlet – a series of traps, monsters, and puzzles devoted to the demon-god Nakresh - and claiming the Shroud as their prize.
