Space Marines - Legio Draconis, The Fluff

Here's the background and army colors for my Space Marines Chapter, Legio Draconis:

Foundation
During their long wars across the galaxy against the Orks, the Crimson Fists were driven off the world of Korrux. The 2nd Company Veterans were left unaccounted for, presumed destroyed in the fierce battles across the planet’s surface. Indeed, the veterans were caught up behind enemy lines and formed a short-lived resistance against the great beast. Between this brief, bloody struggle and the Crimson Fists’ orbital bombardments that followed, only one veteran survived – a sergeant named Aurumvorax.

Near-fatally wounded, Aurumvorax was nursed back to health by a wise hermit—a psychic outcast from the Imperial Administratum. His name, Necronomicus, was taken from an ancient tome of secrets. He now lives on this feral world in his small library in a cloister to the dragon god Bahamut. Aurumvorax became a local hero of the primitive people—a god among men, a feudal warlord in the primitive society. He took a wife—Maliha—and they bore a child, whom they named Bahamut.

The world of Korrux was threatened by primitive beasts, and Aurumvorax became a great beasthunter, protecting the populace in the name of the region’s feudal master. During one such event, Korrux took his holy bolter out to put down a terrible dragon. He failed and was slaughtered by the beast.

Bahamut grew up in the shadow of his father’s legacy, tutored in the ways of the Imperium and the sacred history of the Space Marines by Necronomicus. When he came of age, he and a band of warriors went out into the wilds, and he slew the beast with broadsword and crossbow. He reclaimed his father’s bolter, and Necronomicus determined that it was time to send him out into the galaxy. When the Crimson Fists returned to Korrux seven years later, Bahamut was a lordly master of the feudal planet.

He was taken into the Crimson Fists and impregnated with the same gene seed as his father, the same seed that was injected into the mighty leader Pedro Kantor. Within the Crimson Fists, Bahamut rose through the ranks of tactical squads, veterans, and quickly rose to the rank of Captain. Leading his own company, Bahamut crushed the Ork invasion of Morlock Prime. But all was not well within the Crimson Fists. Bahamut experimented with new combat techniques, diverging from the rigid structures of the Astartes Tactical Treatise. Other Captains were unhappy with Bahamut’s quick progress and how he was favored by Pedro Kantor. Unease was growing.

Eventually, Kantor released Bahamut from service, providing him with half a company of soldiers, a gene seed, and a variety of equipment from the Tech Priests of Mars. Bahamut returned to Korrux and founded a new chapter: Legio Draconis, the Dragon Legion.

Bahamut
Bahamut is cold, hard, and aggressive, but has powerful ethical notions about protecting humanity. He honors the Crimson Fists, though he disagrees with some of their tactics. Nevertheless, the two chapters have been known to work together on more than one occasion.
