Siggy was a Quaddie from the Cay Habitat who worked in Airsystems Maintenance (a yellow shirt and shorts occupation). He helped in the construction of their Clubhouse, doing the ductwork for them and his tastes in literature mostly tended towards "Ninja of the Twin Stars". When the time for rebellion came, he took part in the capture of the D-620 Superjumper; he wanted to do like Colonel Wayne in Nest of Doom and give a rebel yell after cutting through the walls of the ship. Silver, however, suggested they simply enter quietly through a port, which was designed for just such a purpose.
