Fallen

The Fallen are an alien species that fights against the remnants of the human race. They are a nomadic race of pirates who were once part of noble houses. This is evidenced by the banners and flags they still fly even after their fall from nobility. The Fallen Houses have apparently laid claim to all worlds and territories once owned by humanity, and fight the remnants of the human race, and possibly one another, for dominion over these places.

Fallen have 2 pairs of arms and typically wear a helmet with what appears to be respirator devices. There will be some ways that said extra pairs of arms will affect combat. When killed, a Fallen's "soul" escapes it.

Trivia
Their mechanized vehicle units carry overtones of Japanese mecha, and their ships appear like rusted futuristic submarines.

The Fallen have been seen to cooperate with both Cabal and Vex forces, who are in fact enemies with one another as seen on Mars. This suggests that different groups of Fallen will often take different sides in a given war.
