Darth Nihilus

You had travelled far and wide to many planets. While entering a cave, one of the last before you could say you had travelled the entire galaxy, you felt an energy. You had been around jedi before, but this was dark and malevolent. You found a holocron. Triangular. You didn't know the difference between jedi and sith. Touching it. Suddenly. A presence filled your mind. You lost control as you went to a planet you hadn't been before. There, a dark temple was found, pulsating with an unfelt energy. There. You felt the voice in your mind break free. Manifesting in the body of Nihilus. Darth Nihilus.
