Astaroc Cranelson, an accomplished Odivshe Viran and a royal bastard, has never been recognized by the monarchs of Kaldor as family, but that hasn’t really bothered him. But he could yet play a role in the Kaldoric succession.
The Keep on the Borderlands is set in Dyriamarch, a region of Melderyn claimed, but not effectively controlled by that kingdom. There is also a letter meant to be handed to the players before the adventure.
