Legend of the Kinslayer :

 (Y/N) was a loyal Knight of the Round Table and joined at the same time as Mordred. The two hit it off rather quickly with Mordred's passion and tomboyish nature to be just like 'his father'. The two has become almost inseparable always fighting, working and eating together. But as we know, Mordred is a woman...

 He found out by accident on one of their missions when he had to patch up wounded Mordred and after taking off 'his' armor it turned out that his best friend is in fact a female. (Y/N) wasn't swayed by this or rather, he wasn't in a negative way. The two become even closer and (Y/N) was like a shadow and bodyguard for Mordred even if she often pissed off when he told he's devoted to her.

 With passing time Mordred grew colder and angered at Artoria for not noticing her or even accepting her - the only wish she ever had. Her grief turned to anger and she started plotting the fall of her 'father' in order to take the throne for herself. She started to plot and created alliance with those that hated Artoria just like she did.

 She knew that it had to come to this confrontation and one day she approached (Y/N). She had new feelings after spending so much time together... She loved him deeply and was scared of his answer but once she told him of what she was planning he didn't hesitate to answer her call to arms and joined her side.

 On the night before the Battle of Camlann the two confessed, knowing that the next day might be their last. On that very night the two became lovers and spent entire night together. No matter what the knew that they love each other.

 In the very Battle of Camlann, where the Arthurian Legend ends was where (Y/N) earned his title as Kinslayer. Armed with Clamor Tenebris he rushed into the thick of battle, trying to rip the victory out of Artoria's hands. It was on that battlefield that he has slain many of the knights he once called friends without even batting an eye.

 At the end when the bodies of knights were scattered around the battlefield he was met with 'King Arthur himself', armed with Rhongomyniad. When another knight attacked him and got cleaved in half she attacked him. She pierced his chest with her lance... She pierced his very heart. And so, the Kinslayer, fell on the battlefield by the hand of the person he was once the most loyal to...

 After the battle was ended and Mordred was dying she crawled her way to her dead lover and laid down her head on his chest while crying. She died embracing the only person who has always believed in her and was there for her almost all the time...
