Emperor

After a crushing defeat in the Great Hyperspace War, the Emperor had risen up from the remaining Sith Lords to lead his followers on a desperate exodus to the farthest reaches of the galaxy.

There, safely hidden from their enemies on Dromund Kaas, the Sith began to rebuild their Empire. Under the guidance of the Emperor - the immortal and all-powerful savior who still reigned over them even after a thousand years.

The Emperor's palace and fortress was the citadel in Kaas City on Dromund Kaas. This location provided an unassailable meeting place for the Emperor and the twelve hand-picked Sith Lords who made up his Dark Council.(1)

A common depiction of the Emperor was a statue of a man with the face hidden by a hood.
