Author's notes:

This is my first ever fanfic that I wrote. I am not a native English speaker, so forgive me if anything that I write doesn't sound right, however, I have been told many times that I am excellent at writing, in English as well, I will do my best not to let down anyone.

Disclaimer: This story contains an OC as the protagonist, and as it progresses, there may be more OCs introduced. If you want to read the story that has the pre-existing cast only, then this isn't the story for you.

Disclaimer: This story contains depictions of violence and horror. If you are sensitive to reading such content, I suggest you find another story to read.

Oh, and another thing before I start the story. The story is heavily inspired by the story of another video game. However, this is not a crossover as the entire plot, the environment and the characters will come exclusively from the Sonic universe. I will not name the game on which I base this story. That is left for you to recognize, and possibly acquire a sense of delight when you do. The title shall prove enough to recognize the game. Enjoy the fanfic.

Prologue

I suppose I should use this as a notebook. There wasn't much need for it beforehand, however, what precedes me is far from conventional.

My name is Robert Prower. If it occurs that I lose this book, or if, Chaos forbid, my life becomes forfeit, you should search for a fifteen year old fox, about average height for my age, golden fur and brown eyes. At the moment, I am wearing a green, thick winter coat. Hopefully this information will be pertinent by whatever comes next.

As you may have realized by now, I am the son of the reputable Miles Prower. Last I have seen him, he was about thirty years old. A slender fox, unkempt fur, bags under his sky blue eyes. His most prominent feature is his two tails, something he bears as an insignia, and because of that he bears the nickname Tails. Thirty years ago, he and some of his friends were known for repeatedly saving our world from the alleged Doctor Robotnik. The forerunner of these events was the famous Sonic The Hedgehog, a blue hedgehog with emerald green eyes, best known for his vast running speed. My father, then a mere child, apparently was his sidekick, and from the tone of his voice with which he spoke of him, a sort of a big brother figure. Even then, his intelligence and savvy came to aid, and with his two tails he propelled himself of the ground, even if the moments he was airborne were brief. I am not familiar with these events, nor are they related to what I am expecting to find right now.

My father was a distant man, distracted with the creations of his own mind. He was ever so absent during my upbringing, and gradually became more and more scarce as time went on. Around my ninth birthday, he would depart once more, only for him to never emerge again. My mother was, at the very least, devastated when he no longer returned. As for myself, I couldn't have felt anything personal for someone who painted a mere stroke in the canvas of my whole life.

And yet, the most perplexing thing occurred. My mother passed away recently, and a few days after the burial, I received a letter from my father Miles. A man who everyone assumed to be dead all this time sent me a letter from beyond the grave, with pleas for forgiveness. I figure the dead don't have much use for absolution, so I turned my attention to the rest of the contents. There was a key in the envelope and directions to a safe in a bank in Station Square I've never even heard of. I went, as he knew I would, and inside of the safe was a book and research notes. The instructions were to leave no trace that these documents existed, however my curiosity overwhelmed me.

I proceeded to a certain detective agency for analysis, only for them to be just as stumped as me. It would take them a few days to go over all of my father's belongings. In the meantime, I came upon another revelation. I was trying to reach out to my father's friends and acquaintances to check if anyone had contacted him recently, only to find out some of them were unreachable, and those who responded to my calls confirmed that they vanished as well. The most notable of them was Sonic, last seen around a year before my acquisition of the letter. I was later informed of the contents of the safe. The book was indecipherable, however the notes contained coordinates leading to an uninhabited area near Holoska, around the northern cap of this planet. I knew my father had several research stations and workshops, but he never spoke of any research station in the Arctic.

It took me months to book a flight, and within minutes of landing, I was pulling away on a chartered boat. Thus began my twelve hour journey into my father's world.
