In Critical Role: Call of the Netherdeep, you’ll embark on an epic campaign taking players from levels 3-12 as they swirl through strange underwater locales, mysterious ruins, and an intrigue-filled city!
 
Under the ill-fated red moon of Ruidius, you’ll unravel truths of the greatest legends of Critical Role’s world of Exandria™. This uniquely-structured adventure module pairs you alongside rival adventurers, who grow in capability alongside you. In the oasis city of Ank’Harel, secretive and powerful factions invite you into the deeper secrets of the city, and beyond.

A poster map and gazetteer of the city of Ank’Harel, putting its districts, inns, shops, and mysteries at your fingertips
Details of powerful factions with a life of their own, like the scholarly Allegiance of Allsight, the occult Consortium of the Vermilion Dream, and the truth-hunting archivists of the Library of the Cobalt Soul
