===Primarch Discovery===
When Neolithus was discovered by Imperial forces, it was a fledgling space-age civilization with inter-planetary travel, but for some reason vastly advanced defensive capabilities. The Imperial forces fought the primitive but fierce warriors, and faced such resistance that the Iron Rangers had to be called in to support the campaign. Massive, monolithic machines of war, similar to those of the Homo sapiens rotundus, shattered Imperial attackers, and proved difficult for even the Rangers to handle. The Neolithian warriors towered above the Imperial Armymen, and had primitive power-armor that allowed them to hold their own even against the mighty space marines. When the battle went on for such a long time that the Neolithians had begun to steal and repurpose Imperial Battleships, the Emperor decided to call off the attack and personally meet with their leaders to discuss peaceful assimilation. Much to his surprise, Onyx, one of his primarch sons, was the leader of the Neolithian forces. After a long, weighty discussion, Onyx joined his father’s Imperium and Neolithus became an Imperial world.
