consequence - we d need to call the nomads our "brothers" instead of "filthy blue thingy" - but on a more serious note - it was exactly that twist of the story that would mark nomads as the "invaders" at first - only to realize that it were humans that invaded nomad space.
so humans are the aliens here - along with their "unknown origin" from the nomads pov ( since DA decided to cut the introsequence short )
nomads would act against an alien invasion force - desperately choosing deceit cause they wouldn t be able to fight an open war against the rather aggressive humans.
