Harinna's Hold is the primary base of the crusaders of the Sun Refuge. By far the largest settlement within the Refuge, the Hold is home to about two thousand individuals, with another six thousand or so elsewhere on of the island of Madisa.
The castle has massive octagonal outer walls around a towering central spire, with lower buildings in the space between. A complex network of tunnels runs under the entire facility. Harinna's Hold was built to withstand prolonged sieges, though it has never seen any. In addition to its defensive capabilities the fort also serves as the primary temple to Harinna within the Refuge.
