I became stronger in the force then even my master ,but i hid this strength from him because i knew that the strength i had came from a dark hate deep inside me. when my master was called to the battle of Geonosis he made me stay behind and study the archives. He was killed in battle while i was laying in the safety of the temple studying. That is when my hate boiled over. I left the Jedi Temple and took my master's star ship to Tattooine where i killed Sand People to foster my hate for the Sith and Seperatists and to grow stronger in my hate.
