Alleria

Alleria is an ice world used as a penal colony. The planet is mined for its iridium (a dense, very hard, brittle, silvery-white transition metal of the platinum family) by captured criminals. The Juggernauts, including Tournament champion Gorge come from this planet.

A number of Tournament maps are set on Alleria. These maps include: DM-AquaMortis, DM-1on1-Crash, DM-Oceanic

Fauna
Alleria doesn't seem to support a large variety of life due to its cold. The only known native life form is the Allerian Ice Shark, which looks similar to Earth's sharks.

Allerian Ice Sharks have one big dorsal fin, two pectoral fins, two pelvic fins, and a caudal fin. It also has darker, ventral and dorsal finlets. Its head is distinct from its body due to its pointy ridge covering the neck. Underneath the ridge are a number of barbels, and right behind its head are 5 gill openings on either side.

Allerian Ice Sharks appear in DM-Oceanic (UT2003/UT2004) and UC's DM-AquaMortis.
