Earth had exploded exactly five hundred billion years ago.
Humans still live on.
They have evolved.
Now, they live on planets throughout the Universe.
There are ten planets where they live now.
They are called:
Ignis
Aqua
Terra
Aer
Lux
Malum
Vita
Inanis
Mors
and...
Earth 2.0
Each planet has a leader, who in turn is ruled by the Supreme Leader.
They have a common enemy, who is simply called "it".
"It" is a serial killer. It drives people to insanity with a single look.
However, the Supreme Leader had eventually killed it.
Or so everyone thought.
