Tithaarn Temple is a complex of temples at the center of the Aethonite capital of Aeterna. It is the epicenter of Aethon both spiritually and administratively. The complex itself is massive. The Temple sits atop an elevated portion of the city, and can be seen for miles around.

The Temple serves as the primary forum for political proceedings, and houses the high ranking members of the Aethon Order.

The Temple houses the petrified body of the god Tithaar.

The Temple of the Chosen, responsible for the cultivation of Aethon's casters, is also located within the temple grounds.
