Kurn was a Klingon warrior, the son of Mogh, and Worf's younger brother. He is most likely one of the Founders of the Axis Joint Military. His true family name was kept secret until 1438 N.E, when Mogh was accused of being a traitor during the Khitomer Massacre. Kurn later supported Gowron during the Klingon Civil War (notably against the Rebels by Duras, son of Jarod), and afterwards gained a seat on the Klingon High Council. However, he fell from grace when Worf refused to support the Klingon invasion of Cardassia. To regain his honor, his memory was wiped and he assumed a new identity.
