The Transformation of Volstoy
Drunken Dragonborn Cleric
This is the person whose shrine to Bahmut was being shaken down by the Kings Men in your first adventure when you left Stonewall.
Dirk was put in charge of a shrine to Bahmut just north of the pass through the Craig Peaks. The party met him while he was resisting being shaken down by the King’s Men. He sheltered the party as they traveled to and from Walder‘s, who established their secret identities. Later, when the party returned to Stonewall, he showed up ranting about how he was sent by Bahmut to tell them stuff. The world isn’t what it once was. The world they know is like a think sheet of ice on the surface of a pond in the spring. Shortly, the ice will thaw and they will all plunge into the spring, drowning.
