Kallen Kozuki was a half-Japanese, half-Britannian woman who was a captain of the Order of the Black Knights. She piloted a powerful Mech called the Gurran Seidan and used it to destroy a very large number of Mechs and Romulan cruisers. In addition, she fought alongside the Mountain Goat and Raynor's Raiders.
Treav dreamed about being with her on Vulcan and approaching a grave with Teatay's name on it. Knuckonians suddenly rose up from the ground and dragged Treav away, and Kallen's attempts to save him were in vain. Treav awoke before anything else happened.
