Silky LaRoy was found on the planet Ripley by Darth Drakmor in ORC 24,456. He'd found a suitable apprentice in Darth Gangstar, but lost him too soon. LaRoy was so full of rage, and thus a perfect Sith Lord, that Drakmor named him Darth Hater.
Unfortunately, LaRoy was killed and needed a quick replacement. Drakmor turned to LaRoy's brother, Tyrone, and named him Darth Biggums.
