In 1900 immortality was given to every human being by intelligent beings to the 2,000 Plant Earths which contains 2,000 Planets in it's galaxy. It resulted for militarizes to grow increasingly powerful and maintain strong numbers( including the Carthirst Territory). Over the years, it had spread to the Allied Armed Forces then to The Great Alliance Force, causing many planets in so many galaxies to have the better advantage against their rivals. This meant that buildings and transportation vehicles were indestructible no matter how powerful an enemy was. It give them advancements into their technology expanding from sixty seven to one hundred years ahead of its time which made them became more intelligent as immortal humans, another breed of humans who are also like humans.
