Cabal

The Cabal are an alien race with a heavy-set, rhinoceros like appearance. The Cabal are one of many species with the intent to destroy humanity. They are in control of the Dust Palace (also known as the Exclusion Zone) on Mars. Members of the Cabal are known to carry slug throwers or rifle-like weaponry. Concept art shows Cabal working together with Fallen, indicating an alliance between the two races.

Biology
According to concept art, the Cabal appear to be carnivorous as they have sharp, irregular teeth. They are also shown to have wrinkled, gray, leathery skin, a tall skull, wide-set eyes, and a very high, inverted-V-shaped upper lip that exposes the Cabal's upper gums and fangs.

Trivia
A cabal is a group of people united in some close design together, usually to promote their private views or interests in a church, state, or other community, often by intrigue. Usually when organizations are labeled "cabal" it is meant with a dark or sinister intent.
