Moon Nordor is a giant, skull faced Moon which orbits the planet Denebria, and serves as the main base for Flogg and the Mutants.

Nordor was formed when, years ago, the people of Primus blasted off a large chunk of their planet containing an incredibly powerful and evil crystal which they could not destroy. The piece of the Primus was sent off into space, eventually coming into orbit around Denebria, and being christened 'Nordor' by the Mutants.

In modern times, Nordor served as a base for the Mutants. The Mutant Mothership was usually docked there when not out in space, and the base itself contained much of the Mutants weaponry.
