Faenroc, also known as Faenroc the Forgotten, was a powerful Black Legion warlord. In 027.M32 he discovered a Daemon World formed from Warp-infused iron ore. Drilling to the planet's core, he built a vast mine to harvest its wealth for his forces using slave labour. The ore itself proved poisonous, mutating or killing many of the slaves. Faenroc remedied the problem by binding Daemons to his mining machines, making a ritual of mass sacrifice of the entire worker's population for that.
