Call of the Netherdeep

Critical Role: Call of the Netherdeep is a campaign guide and adventure module that will be published by Wizards of the Coast. It is written by Matthew Mercer and Chris Perkins with contributions from James Haeck and features cover art by Minttu Hynninen, interior art by Kent Davis and Linda Lithen, and cartography by Deven Rue. The book will be released in hardcover and digital formats on March 15, 2022.

The adventure, intended to run through levels 3 through 12, begins in Xhorhas, progresses to Ank'Harel, then moves into a new location in Exandria: the Netherdeep, described as "a terrifying cross between the Far Realm and the deep ocean". Under the watchful gaze of Ruidius, which twists fate of those who can change history, adventurers seek to release a forgotten champion of the gods, thought destroyed but instead awakened in his prison in the depths of the world. The book will also include statblocks for new magical items and NPC characters.
