Amid the conflict on Velaraxis, an unlikely force has come to prominence: the **Velaraxian Ironclad**, a hardened Imperial Militia formed almost entirely of Squats, the abhuman descendants of ancient mining clans. The Squats of Velaraxis have lived beneath the planet's surface for millennia, adapting to its harsh environment and thriving in the deep mines. These hardy abhumans have long been employed by the Mechanicum to manage the mining operations of Nexiumite, a resource essential to the war effort. However, as the Horus Heresy engulfed the galaxy, the Squats found themselves dragged into the bloodiest conflict of the age.

Staunchly loyal to the Imperium, though somewhat distrustful of both Imperial and Mechanicum authority, the Velaraxian Ironclad have taken up arms to defend their subterranean homes from the ravages of the Traitor forces. Drawing upon centuries of experience in tunnel warfare and mechanised combat, they have turned the labyrinthine mines and forges of Velaraxis into a fortress network. The Squats fight with unmatched tenacity, employing their advanced technologies and sturdy war machines in defence of their world. Their ranks are bolstered by powerful exo-armoured warriors, heavily armed guild militias, and ancient battle tanks, many of which have been passed down through generations.
