Immortality

In 1900, immortality was given to every human being on the 2,000 Plant Earths which contains 2,000 Planets in its 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 and other forms of matter were indestructible no matter how powerful an enemy was. It enhanced the overall technological advancements of the 2,000 Planet Earths.

Origins
The overall origin of immortality is unknown. However, many immortal people due to their Christian affiliations believe that immortally came down to them from God of The Holy Bible since God, himself, is considered to be an immortal being. The benefits that mortal external humans gain over the mortal humans of Earth come from plentiful special minerals that come from certain parts of their planets' soil and inside mined caves. For example, the mineral zord on Planet Zord.

The events in which people from the 2,000 Planet Earths received immortality is circumstantial at best. People who died much earlier than 1900 did not receive immortality and was only granted to people who were still alive. The only exception is King Eric since he is a unique case. The reason why he was able to keep himself alive for nearly 500 years is unknown. It is understood though that King Eric is not an immortal human since he can still catch illnesses, be injured, and lacks intellectual capacity. Mortal external humans, at least in the case of Neo-Westerners, have extremely low chances of catching virus or illnesses of any kind, except when they die at a very old age of natural causes. With the inability to die from anything, the same can be said for immortal humans. In any case, immortally became widespread to 100% of the galaxy within a mere 30 seconds.

Impact on the Universe
Immortality has made space travel more convenient for immortal and mortal external humans (despite being a bit of technology behind of The 2,000 Planet Earths) alike in addition to:


 * Creating infinite economies without making immortal currency worthless
 * Creating an immortal shield encasing the entire 2,000 Planet Earths, to ensure that any hostile force attempting the invasion of this galaxy can be easily adverted.
 * Technological upgrades in weapons, cars, etc.
 * Creating an incentive to explore and communicate with other galaxies including the other four major ones
 * Creating stockpiles of infinite resources that never run out
 * Special abilities such as infinite stamina, advanced tactical abilities
 * Have an infinite industry
 * Technological advances beyond the imagination of Earthly humans from the Milky Way galaxy.
