Demiurg

"DEMIURG BROTHERHOOD RESPONDING"

– From the Tau Empire trailer for the Battlefleet Gothic vidya

The Demiurg are a client race of the T'au Empire and are described as short, rocky humanoids using huge mining ships to brave asteroid fields to mine.

They're Squats, straight up. Or at least a sensible version of Space Dwarves that doesn't have to be called fucking short in the name.
