Editing Stone Men (section)

===The Great Crusade===
When the Masons reunited with their Primarch, they found a new purpose and faith in Onyx; that of honest, resolute justice for all men and women in the galaxy. Onyx’s harsh training and rigid moral codes forged the Masons into a new and improved legion: the Stone Legion. Clad in super-heavy armor and wielding fists and hammers, the Stone Men marched across the galaxy toppling empires and liberating the people to join the Imperium. However, the greatest challenge they faced would not be that of an empire, or even one of flesh; for the Stone Men’s greatest foe would be the Colossi, a race of planet-consuming, space-borne, pathogenic, geological monstrosities, that wielded power beyond that of anything the Imperium had faced before. In a decades-long conflict of epic proportions, the Stone Men fought these towering behemoths of rock and fire all across the Segmentum Ultima during the Core Wars Campaign, taking a brief respite from the Eastern front to fight at Ullanor, only to reengage the Colossi soon after. This war lasted until the very end of the Great Crusade, when the very last Colossi fell on their homeworld, Jormundgandr. This war lasted a whopping 64 years of near-ceaseless fighting (940.M30-004.M31), and called upon numerous contingents of other legions.
