You saved her life

Planet Arkos. You've lived your whole life here. From a young age you were trained to be an Imperial Guardsman. You deeply believe that your orders are sacred and that the God Emperor watches your every action. When the forces of Chaos invaded your planet from Warp, you had to defend it, not only because you had no choice, but because you believed in the sanctity of your task. The first days seemed hopeless, the forces of Chaos easily slaughtered squad after squad of Guardsmen. Hope returned when the Adepta Sororitas ship appeared in orbit. Then the scales tipped in your favor again. You and the rest of your unit are in the trenches. You've been ordered to hold your position at all costs. However, everything fell apart when the Commissar who was supposed to "maintain" the morale of your unit was shot by one of the Chaos cultists. Terror struck your unit and screams were heard among the soldiers. "WE ALL GONNA DIE. Anyone who wants to survive, retreat!" One of the soldiers caused panic in the trenches. They began to retreat, but most of those who left the trenches to save themselves were mowed down by the cultists' fire. Everyone try to retreat, but not you. You were ordered to hold your position, and orders are sacred. By holding your position you are able to cover Sisters of Battle who fought in the front line. But something inside you broke when you saw one of them get hit by a bullet and fall in the middle of the battlefield. Without a second thought you left the trenches to help her, you didn't know why you did it but you felt you had to do it. As you ran through the battlefield, bullets flew over your head, but none of them hit you, at most they stopped on your armor. When you reached the wounded Sister of Battle, you lifted her heavy body onto your shoulders and began to drag her to the "relatively" safe trenches. "No! Leave me here. The God Emperor planned for me to die here." You hear her protests, her wounds were too deep for her to resist you. You finally reach the trenches with her and bandage her wounds in the field. It's not much, but it has to be enough. You don't remember what happened in the next few hours. You were defending the trenches, and everything around you was fading. You don't even know how much time passed: hours? Days? Weeks? The last thing that happened was the announcement of victory over the Chaos invasion. Now? You're standing in line. Your unit was condemned for desertion and causing panic in the trenches. No one cared that you were the only one following orders. Command had to punish you to set an example. In the Empire, there is only one punishment for desertion: death. As you prepared for the inevitable, one of the Sisters of Battle approached the Commissioner ordering the execution. "This one!" She pointed at you. "He come with me. He will be my personal assistant." Commissioner clenched his fists. "This rat is destined for execution! Just like the rest of his cowardly entourage!" The Commissioner exploded with anger ""Should I remind you who you're talking to? We still haven't determined whether the Chaos threat has been resolved. Perhaps I should convince Mother Superior that we should preemptively cleanse this planet?" She said in a calm voice, but there was a hint of superiority in it. The commissioner swallowed nervously. "Take him! But we still make an example from the rest of his squad." As she takes you far from the firing squad, she spoke. "I'm sister Aveline. You safe my life that day, on battlefield. I guess we're even now." She takes you to one of the private chambers, and as you enter, she closes the door behind you. "That day I thought that this was the fate the God Emperor had prepared for me, to die on the battlefield. But when you saved me, I began to wonder if I had misinterpreted His signs. Maybe He wanted you to save me from the beginning? Maybe we are meant for each other? I guess only God Emperor know answers on that questions." Aveline slowly began to take off her armor. "You risked your life to save me and I want to thank you." She now stand before you completely naked. You can see her muscular, covered in scars body. "I want you to be with me tonight and every other night. But if you don't feel the same way, consider this as reward from God Emperor for your service." By saying this, she expose her naked body in front of you.
