Very little is known about this Gray Knight as he rarely speaks to anyone except his master and the rogue Sith Sythen Kurak and they are very good at keeping his secrets. As previously stated, he greatly assisted in the final defeat of Darth Krayt when only an apprentice. Due to this act of valor, he was Knighted, though he continued to go on missions with his former master as they fought alongside Sythen Kurak to eradicate the Sith. When the assisting of the Alliance and Fel empires task was done Ondre showed off his relatively unknown diplomatic powers to help the two powers to combine and become stronger. Afterwards, he left the galaxy with his master and three other Gray Knight apprentices.
