It was simple.
Simple how the world worked.
In the beginning- there was one universe.
One race-
One fundamental race.
But of course, more sprung forth.
Some contenders.
Others- just a subset of that one race.
But no one- not a single race, and not even the subspecies were capable of matching the sheer intelligence of that one race- the Bromitians- at least for a certain amount of time.
And in time that race got advanced enough to be able to put up a gigantic supercomputer in space and pioneered the age of modern super immersion.
Before that age- they also went through the most horrible war and plague known in the universe's history but that was a different story.
They also developed a new world for themselves. A virtual world where there was no suffering, no pain, a world just like the real one but with much, much greater wonders. New planets- new fun, new powers, new abilities, new- new!
