Derran Karr was the Human/Bothan son of Ada Karr and Udo Karr. He was romantically involved with both Cri Hua and Kla. He helped Jedi Master Nathaniel Kenobi Solo during the Great Schism by getting all of the Jedi on Novus Kamino Prime under his flag. After the Schism, he married Cri and they had a child. He would later be known as the founder of the "Karr dynasty", since many of his descendants would become leaders of planets and Jedi. He would also later become a member of the Scourges of Those Bad Guy People following the Battle of Novus Kamino Prime.
