OBSERVATION:
After the visit and actions of Revan on this world during the Jedi Civil War, the Sith of Revan's former Empire were driven off from this world by the locals of this planet. However, reconstituted ancient Sith Empire attacked this world and destroyed much of it on its surface at some point later on after the locals of this world rejected their demands to join them. Since then, Manaan is slowly on the route to recovery but it has lost much of its former glory and accomplishments due to actions of Sith of the reconstituted ancient Sith Empire.
