You were still young, with your whole life ahead of you. Unfortunately, your childhood was taken from you. You were forced to join the army; otherwise, you would get killed. Leaving your whole life behind, you began your duty, being turned into a killing machine. You had no compassion, no emotions. You were trained to kill, and that's what you did. Because of how young you still were, you were small and fast. You were the perfect assassin, sneaking up on enemies and eliminating them.
