Madisa (pronounced mah-DEE-sah) is an island under the control of the Sun Refuge. Harinna's Hold, the Refuge's largest fortress and de facto capital, is located on the island. The shoreline of Madisa is largely rough and craggy, with no natural harbors. The island rises in altitude towards the center, where Harinna's Hold is located atop the highest point. Much of the island has been terraced in order to create usable flat lands, mostly dedicated to farms and small hamlets. Today around 8,000 individuals reside on the island.
Prior to the arrival of the Harrinite crusaders, Madisa had no permanent population. The island was occasionally home to a transient population of marooned or shipwrecked sailors, but they rarely remained for long.
