Testament was an orphan during the Crusades, and was adopted by Kliff Undersn. When he was old enough, he desired to become a soldier in the war against Gears,and was known in the Holy Orders as the Black Knight. The Post-War Administration Bureau found him frustrated as he became mentally depressed, and offered to transform him into a Gear. He accepted, though unlike most Gears he still retained his sense of self. However, Justice turned him against humanity, and he found himself on the opposite side of the war from which he started.
