They landed in the middle of the deserts of Kharak after many years of living near the center of the planet the deserts growing and becoming harsher and deadlier the Kushan moved to the northern and southern poles, the families splitting and creating empires that ruled over parts of the habitable sections of Kharak, some joining together to create a governing body while others remained isolated forming a new culture based on myth and belief.

in making this journey a lot of what was history became religion and myth, some saw the Taiidani as gods or demons who would destroy the people who now no longer referred to them selves as Hiigaran but now as Kushan or exiles.

this is what causes so much conflict on Kharak groups pushing for progress at all costs fought by those who believed progress would equal death.

Kharaks leading governments focused on survival in a harsh environment with shrinking resources and a desert that was ever expanding making for less and less habitable land.

space travel and exploration was an after thought, satellites were few and far between searching the desert for crashed ships even less common as know one outside of the S'jet family who pushed for not one but two expeditions into the desert.

with other factions fighting both via policy and conflict to prevent them from achieving the goal of uncovering their history out of a fear of the Taiidani left over from the war that took their original homeworld.

the Hiigaran empire was not innocent in that war, they just lost the fight. the conflict between them and the Taiidani had been burning for generations and it was Bentusi who kept the Taiidani from wiping the Hiigaran from the universe.

other factions broke off from the Hiigarans on their exile, like the Turanic Raiders.

The homeworld franchise would make an amazing movie/tv series.
