Kaer Carreg or Karreg is the seat of Lord Harald, and perches on a natural promontory that is slightly separated from the island and reached via a bridge. Kaer Carreg is a wood and stone 'castle', consisting of a stone tower and several buildings that house Harald, his family and household.
Kaer Carreg is functional, housing the household, a kitchen, a great hall and a small armoury. Living quarters are sparse: Harald has a small study/library attached to his quarters (shared with his wife Gisla), whilst Astrid, Sven and Ragnar have rooms of their own. The rest of the household sleep within a curtained area of the Great Hall.
