House of Flass
The House of Flass is a noble family formerly of Mulhorand and currently holding considerable power in Thay. The house has a long and interesting history, dating back to the 4th century DR. Like all great Mulhorandi noble houses, it has its roots in the priest caste.
During the Apportionment of Thavia, the Flass family received a considerable grant in the lands now knows as Flassrin, in the tharch of Eltabbar. The family was slow to renounce their ties to the Mulhorandi priesthood, until matron Nyressa Flass ascended to the position of Zulkir, whereupon she swiftly and effectively excommunicated herself and her house from the Mulhorandi faith.
The Flass family has produced a considerable number of talented Red Wizards, though none besides Nyressa ever served as a Zulkir. The current tharchion of Eltabbar, Dmitra Flass, is a powerful Red Wizard in her own right, and has a better chance that any of her contemporary kin at following in Nyressa's footsteps. However, she has severed all ties to her family name, making it illegal to use it in reference to her.
