Imagen Earth during the year of 3127. There's a sport called Battle Clash that takes place in a huge arena. Battle Clash is a sport where two huge human piloted robots, also called ST's(Standing Tanks), fight until the other ST is offline or incapable of fighting. Now, I don't want Battle Clash or the robots to be what the entire add-on is about, like Gundam or Zoids. The robots are just a part of the story. Now, during this time period, scientists build a inter-dimentional gate, also called the IDG. When the gate is opened, it opens up to a planet, with itself in another dimention, that is in a huge civil war. The planets name is Leto Proxima. Unfortunetly in the relentless spirit of exploration, Earth stupidly enters the planets air space. Unfortunetly, the people that volunteered to explore the new planet, are shot down by unknown origin. A couple more months after the mysterious attack, the US President orders the gate to be shut down. After great debate for two years, the President finally allows the gate to be opened once more. This time, explorers from the other dimention enter Earth's air space. After an extended hand of friendship, the Letonian(what the poeple from Leto Proxima are called) explorer agrees to share historical data and research. It had appeared that the planet had been in civil war for thirty years! The rebels were complaining of not enough rights and freedoms, just as other cultures had done in Earth's history. A couple months after, many Letonian immegrants and refugees had traveled to Earth in search of safety and peace. The president allowed it at first, but as soon as the immegrants and refugees began to overwelm the population of Earth, the president held a meeting with the Letonian leader. After three great years of overpopulation and debate, the Letonian leader finally decided to try and work things out with the rebels. The war ended a month later. So peace and happiness was once again present in both dimentions. The immegrants and refugees returned to Leto Proxima and the gate remained open for future buisness like trade, information, technology, and etc. During this time, rumors and stories were going around telling of the ancient legend of the six chosen. A legend of six chosen individuals, from birth, to free Leto Proxima from war. Also mysteriously, word of another world from another place had been mentioned in the legend as well. Letonian natives looked at Earth as the other world from another place. Legend also spoke of another great war, a war that would clash the two planets into confrentation. So the fate of both worlds was in the hands of the chosen six. Unfortunetly, the Letonian leader did not believe in such stories, so he ignored the constant warnings. Though the rebels and the Letonian government were at peace, there were still some that were not satisfied. They secretly built up their armies, recruiting others to join them. They raided and overwelmed military compounds, steeling whatever piece of weaponry they could get their hands on. It seemed that part of the legend was coming true, but the Letonian leader once again ignored the warnings thinking the raids were just pirates and they would be delt with soon. After a year of faceless raids, the New Letonian Rebelian, or NLR for short, exploded. It attacked the poeple of Leto Proxima, calling them traders and weaklings for giving into the governments of Leto Proxima and Earth. As soon as they captured many space craft, they headed for the gate. Though taken by surprise at first, Earth quickly recovered and attacked the NLR keeping them from entering Earth's atmosphere. Shortly after the new war had begun, the legend had been mostly fulfilled but still, the Letonain leader ignored the legends warnings. All that was left of the legend was the six chosen one's. During the war, the ST's used for the Battle Clash sport were put to use. They were armed with flight capabilities and better weapons. Right after that, the ST's, for the first time, were used for war.
