13th Saint Emiline redeemers aka the Saint Regiment.
Based on the background of a real saint from lexicanum:
Saint Emiline was a citizen of the Imperium who, in M40, gave her life to recapture the world of Emiline's Hope from the forces of Chaos. The planet was subsequently named in her honour when she was declared as a Saint. Her bones are interred at the Order of the Bleeding Hearts abbey on the planet, and reclaiming Emiline's bones became a central feat in the tale of Sister Martika.
M41
Knowledge of this saint is too little, but the citizens of the Shrine World Emilines Hope, guard it well (uknown segmentum, Yarena system). Centuries of piligrimage from the local planets, mark the glorious deeds of the saint a millenia ago. Now in the 41 millenium, the cult is the only Emperyan presence from PDF that is left to the sector, so Astra Militarium decide to form a local regiment force that will recruit from the neighborhood forces.
3 Regiments were drilled and called the 1st 4th and 13th Emiline Regiments. They were supposed to guard the sector and the shrine world.
Hoewever, the Chaos apeteties for this shrine world seems that never stops and a horrible, dark plot was at hand... A rumor started to spread that the Saint was reborn. At this time the sector was in relative peace, and Saints ususaly reborn in time of great struggle. That was the reason of misbelief, but when the Saint revelead herself on the shrine world thousands and hundreds of piligrims rushed to meet the Saint. Local nobles come to see her and quickly became part of hers inner circle and teachings. And the 1st and 2nd Regiment were sent there in case of a riot or even worse scenarios.
Evil Plot is at hand
The saint was... beatiful. But many people forget the old Terra Proverb recorded in the chronicles of Ursh and Merica that: The way to hell is made from good intentions. A large festival in the name of the Saint was held in the name of the saint. At the culmination of the Festival the Saint delcreared that she is gonna make a public prayer. And at this moment the Saint Showed her true colors as servant of the reunions powers. A warp gate was openened and the powers quickly, like a bomb virus started to taint the thousand of pilirgrims that believed in her... now they believed in the warp. Thusand of innocent souls turned into barbaric and frenzied creatures. The Regiments were ordered to open fire and then the Emiline Massacre begin...
Afther the Massacre the regiments moral was so low and half the planet was in the proces of being corrputed. From the horrible warp gate a thousand legions of the The Lost and The Damned started to flood in. Even warbands of the most horrible Chaos Marines were spoted. The 2 regiments dug in, but it was about time to break down. Then the Chaos offered their "mercy" - the 2 regiments must turn traitor or die.
The Saint
The 13th Regiment was sent to deal with the horrible manace that struc the sector. But upon the battle the odds were 3:1. It was then in a major fight in the outskirts of the shrine city, when the batteries of the lasguns were depleted, a female soldier named Emiline shouted to her comrades "Straight Silver, let's knife them to death one of us kill 3 of them". That was a true moment of manifestion of the Emperors own power into a mortal human. Emiline was embraced by light that blindend all. When the Loyalists opened their eyes they saw angel wings that leads them into a fight that looks like a victory.
Redeemers
The shaken soldiers of the 13th regiment, regrouped and inspired by the Miracle, consolidated their forces and charged into a counter attack. Bullets were flying, but somehow did not hit them when the Saint was around. Emilne charged from flank to flank, sloughering chaos servants and space marines alike. Faith and a miracle were not enought to win vs such overlwhleming odds. It was then when the traitors, stunned by shame from their own betrail, hit back their new masters from the rare. The presence of the saint was so strong and they felt redeemed! The 1st and 4th regiment fought the choas untill the last man....
In the end of this cataclismic conflict that no one heard of , the Saint managed to close the Gate, and that cost her life. What remained from the chaos forces was not killed thou. The power of the Emperors presence were so strong that they were all cleared by the taint. From this glorious battle only 13th regiment survived. Now they are known as the Emiline Redeemers and they are sworn to guard the Shrine World for eternity.
Bla bla ... .such a stupod story written in a hurry. Hope you like it thou.
