Raetium is a geographic region in northern Norica. Its boundaries are defined by the Shadowspines to the north, the River Brecclain to the west and south, and the Hollinwood to the east.

The landscape is dominated by sweeping plains devoid of any trees.. The soil is typically poor, and only around the banks of the Brecclain will one find tillable soil.

House Baynes are the overlords of the region.
