Master E-Sumi is a Padjal, and thus does not appear to age past a certain point; his outward appearance remains that of a boy on the cusp of adolescence. His padjali horns take the appearance of a pair of tiny, black bull's horns. In Legacy 1.0 he wore a white-and black tunic with breeches and boots. In A Realm Reborn, he wears a floor-length dark gray-and-black robe, and his facial features have been adjusted to smooth his cheeks and bring more focus on his silvery eyes.
