Prologue
10,000 years ago, all the way back in the technology era, humans were successful, but far too ambitious. Humans even managed to explore new planets, assuming there were any. However, humans believed that they were able to make one large planet to prevent over-population and constant space travel using a material in their possession. Somehow, they succeeded, however after it happened something wiped out a large percentage of the human population and messed up the gravity and the terrain of the whole world. Ever since that day, humans have forbidden the use of most technology therefore the technology was not able to evolve enough to cause more problems to the world hence the new planet was named 'EXTINE SEKAI'.
