Kherubim

History
Kherubim are a race of aliens. They are a coalition of several races with common ancestry. Kherubim come in all shapes and sizes, but generally look pretty much human.

On Earth, the Kherubim and Daemonites have been waging war for a thousand years, using their half-breed spawn and agents to engage in cold wars, proxy wars, and shadow conflicts. The Kherubim, and their followers, answer to Lord Emp on Earth.

They have a specialized taskforce - WildC.A.T.s which combat Daemonites.
