Princesses of the Apocalypse
Riverguard Keep is a long-abandoned keep in the Dessarin Valley on the river. Recently, mercenaries have made it their home and begun to renovate the complex. The party learned from Ogden that the ambush was coordinated by Riverguard Keep, who have sent out parties of mercenaries to find and murder them.
In response, they stormed the keep and are currently setting things on fire and killing everyone who gets in their way as they attempt to find those responsible for these planned attacks.
