From the publisher's website:
When the Decemvirate sends the PCs on a mission into the desolate Mindspin Mountains to retrieve a much-needed alchemical reagent from a hermitic ex-Pathfinder known as the Phitoness of Axioms, the players soon find themselves deep in the mythical howling caves commonly referred to as the Chasm of Screams. Can the brave adventurers survive the harsh environment and defeat the demented thralls of the powerful, icy master of the oft-avoided cavern? Or will their cries of pain join the chorus of tormented voices that already echoes from the Chasm of Screams?
