Squats is Imperium hate speech be better

The species is called the Kin. Basically squats with a new paintjob who live in the galactic core. The Votann are both their first ancestors that left pre-Imerial Earth, and the current Ancestor Core computers that they worship as deities. They are cloned with beneficial stable mutations, resistant to chaos (minimal warp presence), and when they die, they get tossed into the blender where their experience is uploaded into an ancestor core and their biomass is repurposed. They frequently trade with other cultures, and avoid open combat if it would be deemed wasteful.
