Mobius. A world of peace. A place where one could rest easy, knowing that the dangers of yesterday were long gone. The old days of destruction and war were long past. The animal kind lived out their lives in harmony, the young only hearing stories of what times were like long ago. The adults of this time, having lived through it all, would tell their stories with some alterations, as to not scare their children. Today, you could walk the village streets, join in the market events, and the fun and games of the festivals held seasonally. But Mobius wasn't always this way.
Long ago, when Tails was young, this world was in a stranglehold by an evil scientist. Hell bent on ruling the planet in his image, Dr. Eggman created machines that destroyed the homes of many of the peaceful villagers. These monstrous machines were powered by small creatures that Dr. Eggman's henchmen captured. It was a sickening experiment run time and time again on these defenseless creatures before the machines were perfect. Many stood in defense against the machines. Others surrendered to avoid the inevitable.
However, there was one village in particular that caused a lot of trouble for Dr. Eggman's master plan. Knothole. Here lived a rag-tag team of rebels. Some would say they were lead by Princess Sally, while the rest would whisper that it was Sonic that really lead them into battle. Tails would be one of those whispering voices. He was his sidekick, after all. Countless times, Eggman would send his machines to take over the village, and Sonic the Hedgehog, with help from Tails and the others of the village would stop them. These skirmishes became a regular occurrence in Knothole. Eventually, after being on the defensive for so many years, Sonic, who was known as 'the fastest thing alive', was growing old and tired. It wouldn't be long before the machines, who never age or tire, would overcome him, and destroy the village. It was time to go on the offensive, and take Dr. Eggman head on.
Sonic drew up a plan. He brought in only the best soldiers of the village, including Tails, his long time friend who stood by him in every fight, and even saved him when he was in trouble more times than he could remember. Dr. Eggman held himself up in the mecha town of Metropolis. His towering fortress heavily guarded by his most advanced machines. This would not be an easy task. Sonic had no other choice though. He had to do this.
Tails could remember everything that happened after that day. Everything. From invading the fortress, to the numbering forces that stood against them, to the number of casualties they had endured. Half way through the mission, Tails asked himself a question he never thought he'd ask himself. Had Sonic lost his mind? This was a suicide mission. None of them may ever make it out alive. And who was to say they would even succeed? But he didn't have time to find the answers. He was already in the thick of it with the rest of them. There was no turning back.
When they reached the main chamber of Eggman's lair, things happened in a flash. Eggman was known for long winded speeches, always proclaiming victory before the fight even started. But to everyone's surprise, Sonic was in no mood to hear it. He went strait for him. Eggman fell into his large array of consoles, his massive size and girth destroying everything in his fall. Suddenly, the lights went red, alarms started going off. "Warning. Containment of nuclear power cells breached. Evacuate immediately." It was time to go. The place was ready to explode. Whatever Eggman destroyed obviously overloaded something. Tail knew this wasn't part of the plan. They weren't prepared for this.
The team scattered, but Tails turned at the door to see his friend still fighting Eggman. "Sonic! It's going to blow! Let's go!" He yelled.
Sonic stared down Eggman, meeting his angry gaze. "..Go." He said. Tails froze, wide eyed. Sonic really had lost his mind. "Go!" He yelled this time, and then rushed for Eggman, keeping him from escaping. Tails had no choice. He took one final look at his friend as he held Eggamn away from the door.
Outside the tower, the remainder of the team was already there, running into the forest edge. Tails got out at the last second. That's when everything went silent, or at least that's how it seemed. The tower exploded level by level. Fireballs, glass, and rubble falling everywhere. Tails ran to join the rest of the team before turning back to the tower. The fire raged in every level. A ringing in Tails' ears prevented him from hearing one of his teammates. "Let's go! The tower is collapsing!" Tails turned to him, then back again.
"Sonic.." He whispered to himself. It seemed to be in slow motion as the tower fell. His friend was gone, but so was Eggman. There was no way either one of them survived. Tails knew this. Sure, Sonic got out of situations similar to this before, but this was different. He heard it in his voice.
"Go…" It was eerie. Sonic knew too that he wasn't coming home from this.
Ten years had passed by since then. The world of Mobius was safer because of the sacrifice of Tails' long time friend. A statue of Sonic was erected in his honor, and the people of Knothole, and the rest of the villages around the planet, spoke of his bravery. The war was finally over. It was as if everyone could breathe easy again. Children could play without the constant threat of an invasion of machines or risk getting captured.
Tails, on the other hand, felt very uneasy. Since the day he met Sonic, all he did was fight against Dr. Eggman and his machines. Sure there were some times for relaxation and leisure, but they were always short lived. Now, with his friend gone, he felt a void inside of himself. He couldn't place a finger on it, but something just didn't feel right. It was hard for him to really focus on anything. Over time, he felt less and less desire to work on his inventions. The garage he worked in looked as if it had been abandoned years ago. Dust gathered over all of his tools. Knothole just didn't feel the same to him anymore. Yes, he still had other friends there, but none could ever replace Sonic. So Tails had left the village, living out the rest of his days in solitude elsewhere. Alone.
