SM-33

SM-33, nicknamed "Thirty-Three," was a droid pirate who served as First Mate of the starship Onyx Cinder. At some point the Onyx Cinder became buried in a forest on At Attin and by the early New Republic Era. In 9 ABY, a youngling named Wim discovered the Onyx Cinder and, together with three other children named Neel, Fern, and KB, investigated the ship and in the process accidentally activated it and traveled past the barrier, jumped into hyperspace, and eventually became stranded in space. The group of kids then forged an alliance with SM-33 and a force-sensitive man called Jod Na Nawood to find back home and avoid a band of pirates.
