Instead of a single individual, Santa Claus is a hereditary title belonging to gift-givers that has been carried on for many generations. The current Santa, Malcolm Claus, is heading his 70th mission, but his role has largely been reduced to that of a figurehead. Although the traditional sleigh and reindeer were used in the past, they have now been replaced by the S-1, a high-tech vessel operated by hundreds of elves that used advanced equipment and military precision to deliver presents to children. The complex Christmas operations are micromanaged by Malcolm's son, Steve, from underneath the North Pole, while Malcolm's younger son, Arthur, answers the letters to Santa.
