Uncle Crimbo is the Santa Claus-type figure of the
Kingdom of Loathing.
Even though he doesn't have any children, nor any brothers or sisters, he's still an uncle. Purely by the magic of Crimbo.
Unfortunately, Uncle Crimbo has recently had some drinking problems, and his
disgruntled little elves are tired of being exploited and forced to work in the Factory sweatshop wherein all Crimbo toys are made.
