The red granite city of Sele in the Mwangi Expanse was once the site of an ancient Mauxi culture. The city's foundations were built on limestone, and eventually it sank beneath the waters of the Mbernbe River. This may have been a catalyst for the Mauxi migration into Thuvia. The only structure which remains above water—a domed palace—is home to a family of wyverns.1
