Darth Diament (born Horst Larrousse) was a french sith lord. He coined the term Sacre Bleu!
Born on the French planet Bonaparte, Darth Diament became obsessed with the dark side that he bacame a sith himself. However, his overuse of the force turned him into a giant black monster with almost no facial features(which caused him to go blind). This was when he created Sacre Bleu. He was an excellent fighter, but often got punched in the face because he was blind. This eventually led to his death when he fell from a high cliff because he couldnt see it.
