The Sith worlds were a group of worlds in the Outer Rim Territories that were once affiliated with the Sith. These worlds were quarantined during the reign of the Galactic Republic, and some had their histories scrubbed so clean that their denizens were no longer aware of their Sith affiliation. Likewise, it was forbidden for the Jedi to travel to some of these worlds. Exegol was considered one of the Sith worlds despite being in the Unknown Regions. It proved a safe haven for Sith loyalists since worlds like Moraband were known to students of galactic history.
