At the end of the 21st Century, Americans completed the ultimate weapon Orion. However, the scientist Bittner used it and caused a nuclear holocaust on Earth. Those who survived inside shelters went into a cryogenic sleep, waiting for the radioactivity to reach safe levels. 100 years later, only 4500 survived the temporal travel. They built new villages and life went on. You are Zarth from Rimanon. A woman called Mirika came with news of her village having been attacked and her people being taken by the assailant. Rimanon's village chief calls three people, you included, to investigate this case, as Nava is probably the cause of it. Unfortunately, Zarth doesn't have time to take a rest that Nava is already on Rimanon, their many soldiers dropping from airplanes with jet packs on their back, spreading fire and death on the village! Only Zarth and Torald were able to escape the terrible assault. They fled to the Yugg forest and are now the only hope left to stop Nava.
