Va-ga

One of the three races that inhabit the interior of the Earth's moon. The Va-gas are highly cannibalistic and warlike, as most remaining animal life is toxic to them. They are swift and strong quadrupeds, and capable of carrying people upon their backs. The have four limbs, their front limbs function as arms and as legs, they are capable of standing upon their hind legs with the same ease as any human. They have lavender skin that can get almost purple, and skulls that are broader than human skulls but otherwise identical. When the Kalkars invaded they brought one thousand Va-Gas with them, it is unknown how many (if any at all) are on Earth now.
