SM-33, nicknamed "Thirty-Three," was a droid pirate[4] who served as First Mate of the starship Onyx Cinder.[7] At some point the Onyx Cinder became buried in a forest on At Attin and by the early New Republic Era. In 9 ABY,[8] a youngling called Wim discovered the Onyx Cinder and, together with three other children called Neel, Fern and KB, investigated the ship but they accidentally activated it and flew to another planet. 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.[5]
