I am going to start by saying this. If you don't like stories that can be confusing or involve character death, walk away. This is based off of Fate/Stay Night(The game, the manga, and the anime) which gives me the unique opportunity to tell two stories for a single character and have one influence the other(Which those who read my stories regularly know that I love to do, this just gives me a real reason to tie them together). Not to mention to have these two stories I have to have a third as a backstory for the Archer in the first one(seen below). Also, I will be altering some Servant stories slightly, they won't change completely, but it will be little details.

The first story-at least chronologically and not including the one below-is Archer's Torment this uses the Archer that I will be describing below. It is the story of the Archer in the second story and how he has become the version of himself that he is. It will also be telling the story of Assassin as she appears in the second story(Who is not an OC) and may eventually be how you find out who she is(I haven't decided how to share that one yet). The Holy Grail War in this one may pass rapidly because the true interesting part of the story lies afterwards.

The second story is Assassin's Rebirth. It is the story taking the characters from the first into the war. This is where the fun really happens and is the story I truly want to tell. I just can't tell it without telling you the first. As there is a new(ish) character it will change the events quite a bit.

Emiya Shirou lay dying. Each breath was harder and harder to take; the thirty-eight year old man was losing the drive to even try. As he reflected upon his life, Shirou could only think of one thing.

He missed his family.

They weren't a typical family, not by a longshot. But they were his. When on the subject of family, his first thought goes to his father, but Shirou had long accepted his death. Second thought goes to his sister. The small girl had actually been eighteen when she gave her life to save his soul. The body he was in now wasn't even his second. Ilya had granted him a second life using the third magic-Heaven's Feel-to place his soul into a temporary body. His current body was a puppet they found after that.

Next his mind went to his former idol, Tohsaka Rin. She had been one of the greats, having just been offered a position as the head of the Department of Mineralogy in the Clock Tower before everything went wrong.

Rider. The one Servant that stayed, powered-like he himself had been-by her former Master. The Servant had enjoyed her second life, reading every book she could get her hands on and drinking when she felt like it.

And of course, Sakura. His love. The woman who had changed him in ways he never thought possible, the one he had abandoned his cause for. Shirou wanted nothing more than to go back and save her from her fate. If he understood correctly, that was exactly what he was going to do.

Yet, even now he felt the draining of his emotions, the dulling The World had granted him when he had been at his worst.

The accident.

Sakura had too much mana, her circuits were constantly creating more so she could handle it all. The circuits were tearing her apart. Rin came up with a solution she had only read about.

Transplanting magical circuits. Rider and Shirou were so used to her mana there should have been no problem during the process.

They were wrong.

Shirou-as someone whose magical circuits were not really within his 'body' had no problem receiving his share, but when Rider attempted to pull some it conflicted with the circuits within her body and offset both Rider's and Sakura's mana. Combined, the unstable mana killed everything unfamiliar within a ten meter radius, Shirou as someone who had just received the magical circuits that caused the crisis in the first place was unharmed. But the two women hadn't survived the explosion of mana from within them.

Shirou had been so lost in his grief over losing everyone close to him-both physically and emotionally-that when The World offered to remove his pain, he agreed instantly. Since then whenever Shirou felt any emotion it stayed for a few minutes before fading away.

After that with his nearly limitless mana from Sakura's circuits, Shirou decided to go back to his original goal of being an ally of justice. The more Shirou fought for the innocent, the more he had to kill. But he never felt bad about it for long. As Shirou continued to project, his body started to change.

That was when he realized who Archer had been. All the other hints and he didn't notice until his hair had turned white and his skin darkened. Inside of him, hope had sparked. Shirou found what was left of Zouken's notes and studied them all he could. The monstrous creature was gone for good but if he could do it before Sakura had to suffer then it would all be worth it.

As time went by Sakura's magical circuits started to fade, making it harder and harder for Shirou to continue.

And as Emiya Shirou died, one thought went through his mind before the end.

'I can save them all.'

For those who checked this from the start I'm restructuring a bit. One big paragraph seems dull so I rewrote this as a prologue and the first chapter is going to be the original chapter here. Just in case you're paying attention to it outside of any follows I'm gonna add the second chapter as well.
