In the tabletop miniature wargame Warhammer 40,000 Battlefleet Gothic, The Demiurg are a race of squat semi-humanoids, with notable traits shared with the typical Dwarf stereotype. For example they are avid miners, expert traders, in technological advance of humans at least and bear a particular hatred for Greenskins (Orks).

Particularly for the Demiurg it is noted that they reside on the far Eastern Fringe of the Galaxy and also found less often deep in the Cradle of the Galaxy (ie the Galactic Bulge see Bulge (astronomy). They are an uncommon sight being almost purely space-borne in their massive and majestic Commerce Vessels. Their history is unconfirmed, as is their origins, intentions and current threat to others and all is at most shakily based on speculation.

The Demiurg appear to be affiliated in some way with the Tau, although we will wait and see if Games Workshop will decide to transfer the Demiurg concept to the 40k line itself, or whether they will be left as a background race and for the specialist games like Battlefleet Gothic.

It is assumed that the Demiurg are the attempt to re-address the 'space dwarf' image that has not been present since the Squat race that was removed from the game for reasons of the company. Note the Demiurg are an entirely new alien race and are not descended from humans like the Squats were.
