Terastra

Terastra was once one of the largest cities in Estorium. Like most of the rest of the empire, it was devastated during the Illithid War.

In 2959, after Tephra opened a portal to the Far Realm in the Temple of the Mind's Eye in Derenath, the Brightstone Heroes reclaimed the ruins of Terastra to use as their primary base of operations against the aberrations. Many of the buildings were rebuilt, and an earthen wall was magically raised to surround their encampment.
