It is the end of the Indomitus Crusade. A hundred and a handful years of non-stop war against the denizens of the warp and all other foes the Imperium of Mankind under their reborn warmaster, Roboute Guilliman, encountered. It may not have been The Great Crusade, but it was the same idea. To reconquer space for the Imperium that was lost to its enemies. The Unnumbered Sons, de-facto Legionnaires made from Belisarius Cawl genome project - the so called Primaris Marines - having risen to life and war during this crusade. It was the edge in their superior genetics compared to their legacy brethren that allowed the Imperium to triumph over and over and over again. But of course it was also the very fact that Guilliman himself oversaw the planning of this campaign and the new equipment that was delivered to chapters of old and new. After his speech following the Battle of Raukos, he had gathered a group of Astartes that all came from the same batch and yet were unknown of what their original gene-seed was. These Primaris Marines were all warriors of the Indomitus Crusade and had seen through it. This meant that despite their relatively young age, they gathered more valuable battle experience than on any other battlefield. "You are warriors who have excelled in not just aggressive tactics, but also defensive ones. You were fluid as water, and that is what kept your casualties low and your enemies annihilated. You utilized basic training quickly and adapted with your cousins swiftly. Furthermore, you have expanded your relationships outside of the Astartes, having bonded with Imperial Guard Regiments, Battle Sisters and even the Adeptus Mechanicus. Your actions speak volumes of your loyalties to the Imperium you have become to serve as the newest Angels of Death. And due to the trust that other chapters have shown you and the past conflicts in the Segmentum Sol, on Luna to be specific... I shall name you the Luna Legion and shall station you on the very moon of Terra. May you aid the Imperial Fists and Adeptus Mechanicus to tighten the security on my father's throneworld, while the other chapters and I will continue to battle in the depth of the Great Rift. You shall dedicate yourselves in the defense against all threats, so that something like my brother's secret assault on Luna or anything remotely similar will not happen again. Where others fall. You rise!" Roboute announced and explained them, rising his fist into the sky. And with it, so did the assembled, newborn chapter, the Luna Legion. Roaring in victory and glory. And so the Luna Legion had left Raukos and the rest of the Unnumbered Sons to follow their own fate and destiny, having earned their homeworld and permanent position in the Imperium. However, by the time they arrived in the Segmentum Solar it was not ruins they found from the aftermath of Magnus The Reds attack. Instead, Cawl and many servitors once from Mars, now home to Luna, had constructed a massive fortress monastery, various defense installations, military outposts and even an orbital defense and additional elements for their fleet. But beyond that - there were also 500 more Astartes of the same gene-seed ready to join ranks with their brethren. After the orientation, all of the Primaris Marines were gathered in the chapel of their monastery where Belisarius would hold a speech before the Luna Legion. "I must admit my greatest sin was in creating you, the Luna Legion. As much as it may cause confusion, perhaps hate or straight out confusion, I cannot hide this - not from those that I have brought into life and war to protect the Emperor and the rest of these core worlds. From tales and hypnotherapy you know of the arch-traitor, Horus Lupercal. Once the Primarch of the Luna Wolves, then the Sons of Horus and after his death the very same entity being renamed to the Black Legion. That monster and traitor. Is your gene-father. But obsess not with the deeds of evil that had been done. Instead focus on individuals like Garviel Loken who has shown time after time that even as your chapter or legion even falls into the temptation of the dark gods, that a handful of individuals can resist the temptation of the whispers and do the right thing." The reaction amidst the Astartes were mixed. But overall they were happy that their gene-father, the creator of the Primaris Gene, Cawl, had been honest and upfront with them instead of the Astartes giving a chance of finding it out behind his back. But he also warned them to never speak of it outside their chapter, especially with Guilliman having promised swift judgment to those that were made from the heretic legions. Cawl however made the Luna Legion of Horus' seed before the Warmaster made his announcement to only use loyalist seed. At some point their chapter master, Lacrepul Suroh, rose to the occasion and held a speech of unity and brotherhood. Eventually the Astartes settled down the wild emotions in the room and the chaplains started to establish the first steps regards their chapter history and culture so they may never be lost to the temptation of the dark gods - instead respecting their past, owning up to it and together they swore once more: Where Others Fall, We Rise! That was six months ago. Ever since small skirmishes were battled amidst the 4th company, the primary battle company of the Luna Legion, as they had quite a unique structure with 3 veteran companies for example. But the new Neophytes were ready for combat, and the hardened veterans eager to prove themselves. So naturally their captain volunteered to aid the world of Ryza which was under a massive daemon assault. They just had entered warp and were now scattered aboard the mighty strike cruiser Luna's Shadow. It took a warp day, or a week in realspace time, in this case anyhow. Fully battle clad and eager to jump into action the entirety of the company stood ready at the captain's command to be deployed either in united force, or individual squads. The Hangar bay was completely filled with anything from gunships over transporters and tanks to drop pods in an adjacent room. Briefing and Status reports had presented that the whole planet was under attack from all sides. The local guardsmen did all they could, but in the end of the day they would never be able to keep up with insane amounts of daemons. High priority targets for the Adeptus Mechanicus were obviously to secure the manufactorums which were responsible for a lot of warmachines, ammo and regular. The Imperial Guard would obviously appreciate to have their men being dragged out from the horrors they anticipate and fight day in, day out. The Imperial Fists had apparently lost a handful of brothers there a long time ago during a rebuild period erected a shrine with his corpse, weapons and name engraved - which of course the Dornians would have recovered rather than fall into the hands of daemons. Luckily they would be able to reach one of these shrines almost at any position where they deployed.
