Shadow of Camelot
This region tries very hard to distinguish itself from both its Barbarian neighbors, and the Celts of the highland into which it rapidly recedes.
Its one toe-hold on current affairs in the British Isle is the resting place of St. Cuthburt. He was one of the first Christian missionaries to the Isle, and his shrine is widely regarded as the most holy place in the entire island. Because of this, young Abbess Bronwyn of Durham Abbey, just outside of Newcastle Upon Tyne is the effective ruler of the area.
The people are mostly farmers and shepherds. The land is highlands and foggy coast. Despite the holy nature of the region, it was frequently ravaged by kelpies until the past year. However, the disappearance of the water spirits has only led to bolder sorties on behalf of the Brownies that plague the area.
