The County of Ayasofya is a region on the western coast of Hammerfell, on the coast of the Iliac Bay. It is bordered by Tigonus to the north, the Alik'r Desert to the east, Antiphyllos to the south, and Sentinel to the west. On the 2nd of Last Seed, the residents of the area celebrate a holiday known as the Day of Maiden Katrica, in honor of a warrior who saved them during a previous war. The regional capital is the city of Ayasofya City. Redguards ethnically dominate this land. The regional patron deity is Mara, and the dominant vampire bloodline is the Selenu family.
After the event known as The Warp in the West, Ayasofya became part of a greatly-enlarged Sentinel.
