Darth Lithos

Darth Lithos was a Dark Lord of the Sith who led a large population of Sith desertees after the collapse of the Sith Triumvirate. He and his group of about one thousand followers settled on an undiscovered planet known as Lycorax and eventually managed to find enough resources to turn it into a gigantic, 64,000-miles-long starship. They then began to travel throughout the galaxy, secretly gathering more followers.
