Fate/Prince of Shadows.

Updated Chapter 1

Shirou was finally done cleaning his home, he took a moment to admire his work. "Guess I over did it again." He noticed that he could see a clear reflection of himself on his Dojo floor. "I hope the old man likes it this way."

The young Shirou took cleaning as a hobby, as well as Archery. They kept his mind off of the past. It's only been 5 years since that day. He tired to constantly keep himself busy until he passed out. But when that happened, the nightmares came back. They always came back for him. the sound of fire crackling and the phantom smell of burning bodies invaded his mind. They were only just dreams, but they were real to him.

*DING*

His thoughts were stopped by the sound of the doorbell ringing. He quietly walked out of the dojo and towards his front door. "I'm coming!" he yelled so that the person beyond the front door could hear. When he opened the door, he was greeted by a woman with long, violet hair and crimson eyes. She etched something infront of him. he fell asleep right after that.

She caught the sleeping child before he touched the floor. Holding him close to her heart. "I won't leave you…my son.

He failed again, he failed to save Illya and bring her home. Kiritsugu Emiya knows that this will be the last time he will try to save his child from the rest of her family. He knows that he only has a few months left…then he will leave his 12-year-old son, Shirou. As Kiritsugu entered his dining room. He found that he had an uninvited guest, a woman with stunning beauty, a curvaceous body, strikingly red eyes, and long, violet hair. She wore a black business suit and had a very large travel case next to her

"Hello, Magus Killer." She said to him a calming, yet authoritative tone. Kiritsugu put his guard up, he doesn't know who this woman is, but by listening to the way she spoke and her appearance, she must be Scotch-Irish. "Who are you?" he asked her in a calm, but serious voice.

"…You're not long for this world, we both know that curse will take your life soon." Kiritsugu was stunned, how did she know of the curse of Angra Mainyu? "Who are you?" he asked her once more, this time with disbelief, the woman moved to her left to pick up a brief case filled with legal papers, she passed him the first one in her hand, it was DNA test results. She was the mother of Shirou Emiya.

"I am the queen of the Land of Shadows. That should be enough to tell you who I am." She said to the old Magus Killer with a smug look. 'No way' he thought, 'she's…she's Scathach! But how?'

"But how are you even here?" he asked her with a surprised voice, any worry about his son was thought out the window right now. "I've always been in this world; the stories fabricated my disappearance. I've always kept a watchful eye on you commoners, it is the duty of a queen to do so." Scathach said to him in the same tone of voice and the same aura from before, a queen that demanded respect from those of lower classes in society.

"What do you want?" he finally asked her, "What do I want?" she said with a chuckle, "What I want is to be in my son's life. Is that too much to ask for you, Kiritsugu Emiya?" he nodded no to her question. "No, it's not too much to ask." He started to let his guard down, but only slightly, as he walked towards his dining room table and sat down.

He let out a sharp sigh, this wasn't going to be easy to talk about to Shirou. How does one tall their kid is royalty. "Is he asleep?" he asked the queen of Shadows, she answered his question with a nod, Shirou was asleep, she used a sleep rune on him to make sure that he was safe.

"How am going to tell Taiga this?" he exasperated.

"Let me handle it." Scathach said. Kiritsugu quickly asked she would refrain from killing the tiger in human form named Taiga Fujimura.

"For now, I need to see Shirou, I need to make sure that he hasn't taken certain…aspects…from me." She said to him in a somewhat worrying tone. "Like what, if I may ask?"

"…My immortality. My last child may not have had it, but there's always the possibility that Shirou may have inherited it." What? Why would she be worried about Shirou being immortal. Shouldn't immortality be a blessing?

"Wait…" the old Magus Killer thought out loud, placing his right hand over his chin. "When I saved him, there weren't that many burns or injuries on him. even after being crushed under all that debris." Scathach gave him a look that showed nothing but absolute terror before rushing to her son's room. Kiristugu slowly got up and followed.

Scathach cursed under her breath, chastising herself for her immortality and foolishness. "Please don't have it, please don't have it, PLEASE DON'T HAVE IT!" she repeated herself over and over.

When she entered Shirou's room, she quickly deactivated the sleeping run she put on him. he woke up slowly, asking what's going on. Scathach dismissed her son's questions and removed his shirt to scan his body and soul. What she found broke her heart. "No…" she said as tears began to break out from her eyes. "I'm sorry, Shirou…" she said to her son as she began to hug him. "I'm sorry I cursed you…"

Shirou looked at his adoptive father and asked what's going on. Kiritsugu gave him a small smile and said. "Shirou, this is your mother, she's been looking all over for you." Shirou was stunned for a moment before he hugged his mother back.

"Mom, what's wrong?" the 12-year-old Shirou asked his mother. She just continued to cry on his shoulder, not once letting him go or answering his questions. She hated herself right now. Her son was immortal like herself, he would be cursed to forever walk this earth alone, forced to watch as his loved ones all died and turn to dust around him.

She was afraid that he would curse her, be angry at her, and remove himself from her life because of this. She wanted her son to live a fulfilling life, to die satisfied in his achievements and to see his future lover in the afterlife. But her immortality had robbed him of his dream.

Worse of all, the clock tower, and all families with ties to it, will hunt him down, take him away, and experiment on him to achieve the same immortality. 'No' she thought, 'I won't let them take him, I won't let them take away my son.' She hugged him even tighter. Her sobbing settled down, allowing her to catch herself and start answering his questions.

"Shirou, I'm sorry…because of me, you're immortal, or in the early stages of it really. The Mages association will hunt you down because of me. Because of what you are."

Shirou was stunned at his revelation, 'no way, I'm…immortal. Why would mom be upset at his news?'

"Why are you upset mom, shouldn't this be good news to you?" Shirou asked his mother with the naivety of youth. "No Shirou." She said to him as she removed her head from his left shoulder to look at her son right in the eye.

"I am Scathach, the immortal Queen of the Land of Shadows. You are its prince…that makes you a prime target for any Magus in the area, or in your life in general." She looked down for a brief moment, she knows there's only one thing she can do, it's what any good parent would do. "Tomorrow I will begin your training. I won't let any of those Clocktower dogs take you from me."

Late into the night, Scathach walked into her son's room, she felt that he was unwell. She saw that he was sweating hard through the covers and his clothes. She quietly laid down next to him and held his head close to her heart once more, resting her chin on his head.

"I won't let those monster's take you from me…I won't." She whispered and petted his hair, calming him down and drawing back his nightmares. She knew all to well what atrocities the Mages Association is capable of doing. She's had to clean up a few of their messes in her long life. She knew she'd have a long time to train her son, her little Prince of Shadows.

Hello Everyone, you're probably confused, this is something that someone requested me to write. This is a Saber route story, but Shirou won't have any relationships with the Matou's or Tohsaka's because of their clocktower relations. There's no way in hell that Scathach would allow her son to be anywhere near them.

I've already got a story board ready for this one, it will be a one shot series, no I'm not abandoning my trilogy that is Fate/Darkness, ShirouxLawfull Good Morgan is just taking a break right now, I don't want to leave it unfinished.

Please leave a review if you like what I've written so far.

Update:3/5/2020. I've changed and added a few things to make sure the timeline is right. I was wrong about how old Shirou was when Kiristugu died. He was actually 12, not 14.
