heya, so, um, what was his name? micah or something? anyway, what was his story? why was he gone? i remember there being an episode where he shows up, but then he doesn't stay... why? was he human? or did he have powers like glimmer?

any and all answers to my questions are most appreciated... oh, and does anyone have a picture of him, or some fan art/customs of him?

thanks all!
