Darth Octillious was originally born on Iridonia as Tu’hil Urbek in the year 67 BBY. Trained by Darth Sidious, he became a deadly Sith apprentice. It was only natural that when a planet inhabited by Force-sensitives appeared that he would want to recruit more to his side. This planet happened to be Nonderan. On the forest world of Nonderan he hired Dark Jedi to attack cities and Jedi. This led to the Jedi finding him. Eventually he left the planet with his followers and traveled throughout the galaxy to kill lone Jedi.
