Prologue
Its the 71st century. However the present world is not a pleasant world were humans have complete over everything and are spending their days peacefully, but one were humans are hunted, killed and preyed on by their own creations. It all began during the 50th century when the rich and influential countries formed and alliance and started a war against the weak and poor countries and any other country that opposed them. But, it was only a war on the outside. In the inside, it was nothing more than a campaign of the rich countries to destroy all opposing forces and to devour the resources of the poor countries. Though the rich and the influential countries were winning the war with their with their vast armies and arsenal of weapons, they became greedy and wanted to dominate the poor countries even more. They deceided to do that by every millitary and opposing forces of those countries. They decided to do that by creating genetically enhanced soldiers and each of whom would be equal to almost 100 soldiers. These soldiers will not posess any feelings or will except ferocity and visciousness. The scientists of those countries or more specifically, the biologists started to develop these soldiers. But, they made two grave mistakes in their development. In the genes of these soldiers, they forgot to insert the gene of obedience and inserted the gene of intelligence. In other words, they created nothing other than intelligent and viscious superhuman beings that would be the cause of their doom. The scientists didn't notice these two mistakes and thought that since these soldiers would be very obedient, they wouldn't do anything against their creators and would truly be invincible. Then, on the fateful day that they were developed and released in the battlefield to wreak havoc, these soldiers did wreak havoc. However, in a really different sense than the rulers and the scientists of the rich countries thought. These soldiers didn't only obliterate the opposing soldiers, but every single soldier and human being they could find on the battlefield. And after that, they began their endless conquest of the universe and turning any planet they conquered into parts of their empire.
It has been almost 2000 years since then. These soldiers are now known as The Grineer, owners of almost half of the solar system and the humans are their slaves. After the incident 2000 years ago, the Grineer have mass produced themselves. Although their appearance and life span have degraded tremendously, their intelligence and strength cannot be compared to that time. The solar system is now ruled by four factions and they are: The Grineer, The Corpus, The Sentinents and The Orokin. The humans are not even considered as a race now due to their extremely low numbers. However, unknown to the ruling races, a man named Tenshin was raising warriors in extreme secrecy to fight the Grineer and put a stop to their endless conquest. He is a master of Tennryuu, a style that combines every form of martial arts that is there on the earth and his students are some teenagers. They are the Tenno( practitioners of Tennoryuu). Warriors who follow the Old ways and are masters of the sword and the gun. And one day, they began their move. They started by assassinating the Grineer leaders in the earth and within the short span of five years, almost every Grineer leader that on earth was assassinated. In this fashion 200 years passed by. The situation has drastically changed since then. Now, the Tenno are one of the ruling races. The Tenno have now increased in number and do not live or teach in secrecy. Although the Grineer court knew where the Tenno resided, they didn't dare to send any force to eleiminate the Tenno, for the Orokin favoured them and to pick a fight with the Tenno was like picking a fight with the Orokin. And the Grineer feared the Orokin due to their knowledge and weapons. To support the Tenno cause, the orokin gave them some armors. However, these were not oridinary armors, they were known as warframes. And each warframe had four unique abilities along with various other powers and features. This took the Tenno to a new height of power. But, only the most skilled and powerful Tenno were allowed to use the warframes. Due to the attacks of the Warframe-clad Tenno, the Grineer influence was almost halved in the next 50 years, making the Grineer more fearful of the Tenno. In these 50 years, one another thing changed, only those who can use warframes are now called the tenno and those who couldn't were Tenno trainees. The Sentinents again started a war against the Orokin. But this time they took the support of the Grineer. The Orokin asked for the support of the Tenno and they agreed. The Tenno thought that this war would be easily won, thaks to the powers of the warframes. However, something rather unfortunate happened at the war; almost every Tenno that went to the battlefield was defeated. Thus the Sentinents won the war. The Tenno who survived were put into cryopods and tossed into the void by the Orokin as a last resort. The Sentinets knew of this and The Sentinent king, Hunhow gave his daughter Natah the task to find and kill the Tenno who were tossed into the void. As for the ones who were captured, they were tranferred to grineer prison cells and their warframes were confisticated. Natah, however, didn't listen to her father andinstead kiling the warframes in the cryopods, she woke one up and decided to revive the Tenno. for what purpose she did this, was unknown. And it must be fate that she had awoken the most skilled Tenno and the user of the Excalibur warframe, Katsuragi Ryuunosuke. Together, they embarked on a mission to awake and free the Tenno who survived and do waht they are supposed to.
