Space Dwarfs!

Dwarfs

After turning the shoggoths against the Elder Race and winning their freedom, the Primordial Ones extended dominion over the entire planet. Eventually the needs of their antediluvian science demanded resources not to be found on Abbith, and they cast their covetous gaze towards the stars. The Primordial Ones created the Dwarfs to withstand the rigors of space and harvest the resources of the galaxy. For generations they were launched in rockets towards all observable asteroids, exo-planets , and other stellar phenomena. These forge ships contained clusters of dwarfs in stasis that would awake on impact and be genetically driven to seek out resources, extract them, and use the forge ship to send the riches back to Abbith (though not the dwarfs, who were considered expendable.) Designed to single-mindedly exploit the resources of anything they landed on, the dwarfs were physically bred for hard labor and wired to obliterate whatever stood in the way.

This of course led to the destruction of the Primordial Ones, when a fleet of forge ships programmed to return to Abbith filled with the mineral wealth of alien planets, was instead filled with the centipede shock troops of the Yekubians. The vanguard of a much larger invasion force, bent on the destruction of whatever arrogant race sent the psychotic dwarf ships to the planet Yekub.

After the destruction of their makers, hundreds of thousands of Dwarfs were suddenly cut off from the genetic signal amplifiers that gave them purpose. Some were aboard ships bound for distant stars, others in the middle of complex mining operations or plundering the ruins of destroyed civilizations. While others still were locked in genocidal battles with alien species.

Over the millennia, these isolated groups have formed their own societies with unique cultures and ambitions. Dwarfs may be found throughout the galaxy, some still packed into forge ships bound for an unsuspecting planet. Others have built advanced spacefaring civilizations of their own, and seek out the remaining dwarfs to bring them into the fold. While still others toil away in isolation, unable to shake the basic single minded purpose of death and extraction that is after all, in their blood.

Dwarfs are short and stocky, with overly large heads and tiny hands.  They tend to have hirsute faces, but lack any hair over the rest of the body. They have no sex, and are incapable of breeding. They can live for thousands of years, although typically environmental or mental factors lead to early deaths.
