Darth Silas was a freakin' awesome example of a species which was somehow, sadly, related to Darth Maul. He was sent out by Gonk to seize a very valuable painting and use it to whack some American professor ober de head with it. Darth Silas was very successful in all his missions, raping elderly nuns and fucking them to death. He had a thing for milfs, clearly, which made him extremely energetic for his business. He was almost successful in defeating his American enemies until he was kidnapped by some whiny professor and shoved into the backseat of some car. He later escaped and was shot to death in a Paris back alley. Shame.
His legacy later lived on in Star Wars Episode XIIIII: The Monkish Loser.
