Ulleus
Ulleus was an Ultramarines Vanguard Lieutenant, who was among the Chapter's forces that took part in the War of Beasts.
However Chapter Master Calgar charged several strike forces with seeking out any allies or foes in the Vigilus System and Ulleus became second-in-command of a force led by Captain Acheran, as he sought the status of the Industrial World Nemendghast. When they arrived at the world, aboard the Strike Cruiser Carpatia, the strike force intercepted signals from Nemendghast's surface that informed them it had fallen to Heresy. However the smog covering the world's atmosphere, prevented the strike force from determining the true extent of its fall and Acheran ordered an immediate deployment to Nemendghast's surface. What they discovered was a hellish world, whose factories that had been remade by the Black Legion to create Daemon Engines and Possessed Chaos Space Marines. Though they were vastly outnumbered, Acheran refused to leave and instead ordered an attack to destroy the Daemon factories. The strike force was able to use explosives to destroy the Daemon factories, but the Black Legion made them pay in blood each time they did. Soon only a small fraction of the strike force remained, as they began attacking the Black Legion's main factory known as the Forge Infernus. However Acheran knew given the Infernus' size, they would need time to fully plant the explosives in key areas to ensure the forge was destroyed. In order for them to succeed, the Captain tasked Ulleus with leading a small force to draw the pursuing Black Legion away from the main strike force. Even knowing he was being sent to die, Ulleus performed his duty and the Lieutenant's force held off several waves of the Black Legion's attacks, before they were torn apart by a horde of Venomcrawlers. However his sacrifice, gave Captain Acheran and the strike force the time they needed, to destroy the Forge Infernus.[1]
