The Tarellian are a species of doglike humanoids, known as “dog-soldiers,” that are near-extinct due to multiple threats against their species. They possess broad shoulders and a voracious maw in the shape of a canine’s. They once had a thriving civilization before Mankind virus-bombed many of their planets during the late 30th Millennium. In the 40th Millennium, the tyranids destroyed one of their last remaining planets. The remaining survivors are from sparse mercenary and nomadic populations that drift amongst the stars. The Tau have employed many of the remaining Tarellian into their ranks as mercenaries, or adopted them into their society.
