The Sith Clan "OD" at one point or another created temples and strong holds in Planet Bosthirda and Ziost. As of right now they have returned to planet Roon but have left stakes in Ziost. They also created a massive space station which now has been taken to the unknown regions named "The Sarlacc".
An Academy is being erected in Planet Roon for future disciples of the Sith path. All Dark Path walkers are welcomed to our libraries and studies.
