The village of Isaia lies in the far northern reaches of Sapience. The upper village is contained within a large ice cave and boasts a thriving merchants' district. Beneath the ice in the frigid ocean waters is Lower Isaia, which contains the palace of Queen Denaye, a temple, and several smaller structures.
The Isaians are humanoid in appearance with pale radiant skin and dark hair. Young Isaians, unlike their adult counterparts, have slightly webbed hands and feet. These vestigial structures may suggest that Isaians were once exclusively ocean dwellers.
