I'm back, and I've been thinking about reworking/tweaking the Chapter a bit, and I would appreciate some feedback if possible. With this in mind, I present the new history of Cosimar and the founding of the Revenant Children.
Cosimar is a feudal world located deep within the confines of Segmentum Obscurus, it was first discovered by the Imperial Fists Legion during the Great Crusade, shortly before the Imperial victory at Ullanor against the Orks.
When the Fists first arrived at Cosimar they came with the intent of exterminating the entire culture of Cosimar as a whole, bent on converting the planet to the vision of the Emperor with nary a regard for the rich and ancient culture of the world, a fact that the voivodes of the planet did not take too lightly. The people of Cosimar resisted compliance with all their rage and might, but their numbers and skills paled in comparison to the VIIth Legion, and Cosimar was brought into compliance by force.
Cosimar would then become a bastion of resistance against the Warmaster during the events of the Horus Heresy, with the Arch-Traitor sending his most elite forces led by Abaddon himself to claim the planet. The ensuing battle nearly resulted in the planet’s destruction, but in the end the traitor forces prevailed and claimed Cosimar for themselves. It would not be until the event known as “The Scouring” that the Blood Angels Chapter would re-conquer Cosimar and save its people from the tyrannical rule of the Sons of Horus; after purging the planet of all chaotic corruption, the Angels would claim the planet for themselves, much to the chagrin of the sons of Rogal Dorn.
The children of Sanguinius would latter leave a portion of their forces stationed at the planet, which would latter be founded into the Revenant Children Space Marine Chapter at the beginning of the 34th millennium. Cosimar would enjoy a period of prosperity after its reconquering, but it would seem that the purge that the Blood Angels enacted upon the world was not as thorough as they thought, for several centuries later, on the eve of the 36th millennium, Cosimar would be hit by a violent Warp Storm that would latter become known as “The Bloodstorm”, which would bring with it the nightmarish creatures known only as “The Striga”, fearful abominations that, although feral, struck the planet’s human populace hard and fast, attacking at nightfall and draining the populace of their vitae.
The Revenant Children would take personal offence against these warp-borne abominations, and would enact a second purge of the planet, alongside the aid of the human inhabitants of the planet, to purge the Striga from existence all together.
The following event would become known as “The War of the Striga”, a period in Cosimaran history where the forces of the Revenant Children Chapter would ally with the humans of Cosimar in order to purge the planet of the nightmarish monsters spawned by the Bloodstorm. The Children and their mortal allies would succeed in their endeavors, but not without suffering heavy casualties in return. With the Striga banished from the world, the Astartes would be left too drained of resources and manpower to continue prosecuting their vigil over the world, so it would be then, that the Astartes would give the people of Cosimar the rights of self-governance, so long as they maintained a pact of swearing fealty to the Imperium and supplied the Chapter with fresh recruits.
Thus, the Knightly Orders wound be founded upon the soil of Cosimar, warrior organizations that would take the mantle of defenders of the planet from the Revenant Children while the latter regrouped and strengthened their numbers over time.
