Nemendghast is an Industrial World that surrounded by an asteroid girdle that lies on the edge of the Vigilus System. It was once colonized by the Imperium, but this ended during the War of Beasts, when it was invaded by the Black Legion Warband of Vorash Soulflayer.
The Warband then created a flesh-factory known as the Forge Infernus, but their invasion would not go undiscovered for long. The Ultramarines would soon come to Vigilus's aid, as the War of Beasts raged on, but they dispatched patrols to scout the System. One patrol led by the Librarian Maltis, discovered Nemendghast had fallen to Vorash's Warband and the creation of the Forge Infernus. He then led his patrol against the Warband and though they were outnumbered, the Ultramarines managed to cripple the Forge. However, only Maltis was able to escape and warn Chapter Master Calgar of the threat lurking at the edge of the Vigilus System.
