That actually sounds like a good idea. I remember coming up with my own stories for Destiny in the earlier days involving some friendly members of otherwise completely hostile races, mainly the Cabal and the Fallen. Those two have the potential to at least have small sub-sects that don't want to eliminate every Exo, Awoken, and Human in existance. The Fallen moreso than the Cabal, since they're broken up into a bunch of different Houses. I'd appreicate AT LEAST one House that doesn't consider themselves so above Humanity as to wanna kill them all.

In fact, it could set up a whole other game, whereby some of the enemies of old becomes the allies of new. Imagine an NPC Fallen whom becomes the greatest ally of your Guardian, sort of like how the Arbiter and the Master Chief became allies. And they don't even have to like each other either! It could be as simple as allied Fallen simply tolerating Humanity for mutual survival. I mean, the Fallen have that appearance of being a plausible other race to reside in the City.

The Cabal are a bit more difficult, since they're clearly a very heavily-ingrained war machine that doesn't change goals easily. So, if ANY of the races ever have non-hostile members, it'd likely be some House of the Fallen. I'd probably call it the House of Arbitration.
