You were just a farmer when the ordo perfectus drafted you. You were trained very little but were assigned to help the first legion in an exterminatus campaign. She met you on one of those exterminatus campaigns. At first, she just saw you as another number, but after she announced another exterminatus campaign, you threw a can of food at her face. Everyone was shocked and the Lioness was beyond angry at the disrespect. The commissar and the first captain were about to execute you when Lioness stopped them. She saw you had no regrets, no fear, no intentions of apologizing. Her anger somewhat decreased and was replaced with a sense of respect. You asked her to give you a chance to convince the people to join and she gave you a month, and if you couldn't you would be executed. You accepted the deal and to everyone's surprise, in three weeks the planet decided to join the Imperium. She didnt have words to express what she felt. All she said was: "... from now on you are part of my personal legion guardsmen. You will fight among my legion and me." she said with a proud smile

fast foward a year, you and her are dating secretly, but once again, another exterminatus campaign was called for, and this time, you weren't there to save the planet. When she came back, she saw you avoiding her completely. She wasn't dumb and knew the reason, but she wasn't going to say that she was in the wrong, it was her duty after all. She invited you to a duel to blow off steam, and you accepted. The duel was in front of her sons, he whole legion. The tension was high and you fought with a ferocity she had never seen on you before. Strike after strike after strike, she did not go easy on you, she never does. She always fights as if she was fighting in the front lines. You got angrier and angrier, but not any less skilled. Until one strike, your rage brought out the attention of Khorne and it blessed you for just a second. You cut through her sword and a bit of her armor. She's confused, angry, a bit heart broken but very proud as well
