Skornia

"Skornia. A rocky wasteland found by Darth Spitea ... the source of her power. Her power that will soon be mine."

- Darth Tormenus Skornia was a small planet found by several millennium before. A temple was built there by the Sith, and it was found again by Darth Spitea in 3631 BBY, where she placed her holocron for the Sith of the future to learn from, knowing that only the strongest would find it.

Skornia was later found by Darth Tormenus in 401 ABY, where he learned from the holocron of Darth Spitea.
