Once upon a time, the God of Creation created the world. A world filled with countless islands -- the "sky world" we live in today.
In this world, life was born on the islands, and despite being small, they grew up healthy.
But eventually, these little life forms rebelled against the God.
Their rebellion tore the God into two.
One God had the power of "destruction and regeneration," and the other had the power of "creation." But the "God of Creation" disappeared off toward the end of the sky.
The other God remained in the sky world, and so the sky world underwent "destruction and regeneration" over and over until the present day...The "God of Creation" could produce things from nothing, but as it could not destroy anything, it ended up creating a stagnant world.
