Simoth, a planet covered in forests, was the location of a camp inhabited by Simothian enslavers. Darth Caldoth, a Sith Lord, left Ry Nymbis, whom he had chosen as his apprentice, in this camp on Simoth. Nymbis spent seven years battling for the enslavers, which made him more powerful. After this time, Darth Caldoth came back, slaughtered all of the enslavers, and was then attacked by an enraged Nymbis, who was defeated. Pleased with his apprentice's progress, Caldoth took him from Simoth to continue his training.
