Unlike many of the other primarchs, Konrad Curze was not taken in by any family and was left to raise himself in the vast underhive of Nostramo Quintus. Crime ran mostly unchecked, clinical depression was inescapable for most because of the constant darkness, and overpopulation was kept in check more by suicide than by any other measure. The vast majority of the planet's population lived in abject poverty, toiling in the mines while the rich grew in affluence, exploiting the already downtrodden workers. The crust of Nostramo bore high quantities of the strategic mineral adamantium, which provided the basis of the planet's immense mining and refining industries and supported the economies of its large hive cities. Nostramo was a Human-settled world that circled a dying sun whose light now only barely reached the world, leaving it trapped in perpetual darkness. Theoretically, the only way the Primarch could have reached the surface was to have swum through molten metal or had his gestation capsule borne upwards through volcanic vents to the surface. The cratered pit his descent had carved into the planet was closed over and later regarded with fear and suspicion. His descent left a scar in the virtually inviolable adamantium strata of Nostramo, the result of the supernaturally resilient primarch's violent birth into a world that knew no light. His embryonic form's gestation capsule, cruelly ripped through the Warp from distant Terra by the machinations of the Chaos Gods, impacted on the dense cityscape of the planet's largest hive city, Nostramo Quintus, smashing through countless levels of urban debris and mouldering architecture, through the planet's crust and into its geosphere before finally coming to a halt near the highly unstable liquid core of the planet. From the Arcana Progenitum of Nostramo Quintus, detailing the arrival of the infant Primarch Konrad Curze upon NostramoДЄncient Remembrancer sketch of Konrad Curze, the Night Haunter, Primarch of the Night Lords Legion illustration taken from Carpinus' Speculum Historiale.ДЄccording to the heretical handwritten chronicle of his life, entitled simply The Dark, the Primarch Konrad Curze's earliest memory was of descending from the heavens in a crackling ball of light to the night-shrouded planet of Nostramo. It was a daemon, no less, with the body of an infant but the expression of an old man, its eyes black and cold as obsidian.' a glowing child-form it was, crawled from the Pit onto the broken street, hissing molten metal dripping from its limbs. Konrad Curze and his Night Lords Legion were shaped by the terror of darkness on their homeworld of Nostramo, just as much as they were by the gene-craft of the Emperor.

Konrad Curze was from the start a dark and haunted figure, obsessed by death and judgement, and unshakable in his belief in the fundamental fallibility of Humanity and the agency of fear as the only true means of controlling Mankind's failings. His VIII th Legion, without his leadership, then broke up into competing warbands of Heretic Astartes and fled into the Eye of Terror with the rest of the Traitor Legions. He was slain, some believe willingly, by the Callidus Assassin M'Shen on the world of Tsagualsa in the Eastern Fringe of the galaxy immediately following the end of the Horus Heresy in the early 31st Millennium. Night Haunter did not enjoy his role as an Imperial war leader and was the only one of the primarchs who showed little affection for his 'sons,' the Space Marines of the VIII th Legion that had been created from his genetic template. He was a brutal warrior who believed in the use of fear as the most potent weapon against one's foes, and he taught his Astartes to be as brutal and savage as necessary to put down the enemy. His psyche damaged by the difficulties of his early life, Curze never recovered his mental balance and sought only oblivion from the pain of his reality. Night Haunter was tortured all his life by terrible, dark visions of the future, and this generated a level of psychic anguish and despair that set him apart from his fellow Primarchs. Konrad Curze, better known as Night Haunter, the name he preferred, and sometimes as the 'Dark King,' was one of the 20 superhuman primarchs created by the Emperor of Mankind in the late 30th Millennium and was the master of the Traitor Legion of Chaos Space Marines known as the Night Lords. Primarch Konrad Curze, the 'Night Haunter.' ' It is better by far to be an object of fear than of respect, for one is a truth of the soul and the other an illusion of the mind.'
