Ever since Squats (essentially 'space dwarves') were subtly reintroduced to the Warhammer 40K canon in the Battlefleet Gothic 'Armada' expansion as the Demiurg (nomadic astral miners, resource-gatherers, & tech-traders), I've wondered what their ground forces might look like. Armada describes the Demiurg's fighter craft as being repurposed mining vehicles & droids, & my friend Dom & I have discussed how they would probably make extensive use of droids if pushed into direct combat. There are quite a few 'space dwarf' figures available on the market nowadays to fill the Squat-shaped gap from the old-school days of W40K; but my favourite has to be the incredible Grymn range from Hasslefree Miniatures, which is where all these figures are sourced from.
Demiurg ships in BfG are quite powerful, & are basically mobile refineries & manufactories, but not that large in mass; & I imagine even with fewer decks, a large proportion of their systems are automated or controlled by droids. With no religious other other hinderances to technological development, I see the Demiurg as ahead of the Imperium in this regard - also because the Tau are described as having acquired ion cannon technology from the Demiurg, & their trademark weapon in BfG is the cutting beam, usually used for rendering down large asteroids, & which is empowered by collected matter from spatial gas clouds. For this reason I'm thinking of saying these figures are armed with 'ion beamers' instead of bolters, for a bit more flavour. These would fire sustained cutting beams that could do a little damage to a couple enemies, or a concentrated attack on a single foe. One of the Hearthguard has a power fist, one has a chainfist, & the other has lightning claws & a grav-pack (counts as a jump pack). These Hearthguard are the personal guard of the Guildmaster of the Brotherhood, who I'll probably round off this little force with a character figure for.
Next up, the much-larger Demiurg wardroids that I'm working on..
