Trul Zednacker was found on the planet Marmalade by Darth Sweetums and seduced by the Dark Side almost instantaneously. Christened as Darth Scat, he was a fearsome Sith Lord. He murdered Sweetums sixteen years later in ORC 24,868.
Later that same year, he found Darth Hilter and began training him in the Sith arts. After being partners for 27 years, Hilter killed his master too.
