Planet X (Sky Pirates!)

Planet X was a planet inhabited by the Sloathes that breached the wall of the System. It was fitted with telescopes for the Sloathes to monitor the System as they pirated treasures and brought them back to the tunnels of Planet X. Eventually, what had been the Most Supreme Captain Trenkor Lep returned to Planet X, ate all the other Sloathes, and then proceeded to control the planet and move it towards the System's sun. When the System collapsed and formed a planet in the real universe, Planet X became its moon. (PROSE: Sky Pirates!)
