Atrithau was the ancient administrative and commercial capital of what was once Eämnor, and one of two Norsirai cities to have survived the Apocalypse. Atrithau is peculiar in that it is built upon what is called “anarcane ground,” which is to say, ground that renders sorcery impotent, found at the foot of Mount Ankulakai. It was originally founded c. 570 as the fortress Ara-Etrith (“New Etrith”) by the famed Ûmeri God-King Carû-Ongonean.
