Grelz is a duchy inhabited by a people closely related to those of Unkerlant, but different in various cultural traits and speaking significantly different dialect. Grelz was located in southern Unkerlant, giving it harsh winters due to its close proximity to the south pole. Once ruled by Algarvian merchant princes and bandit chiefs, Grelz had been incorporated within Unkerlant for centuries, and despite thinking of themselves as different to other Unkerlanters the Grelzers had no active separatist tendencies.
