Return of the Netherese cities

Era beginning/end

The flying enclave of Thultanthar had shifted in its entirety into the Plane of Shadow the day before Karsus' Folly and remained there until the year 1372 DR when the enclave returned to the Prime Material Plane with the goal of reestablishing the Empire. The Netherese expanded their new empire for the next 113 years, establishing Sembia as a protectorate. In 1487 DR, Thultanthar was brought to ground by Elminster Aumar. It fell upon Myth Drannor, destroying both cities.
