It all started from a meteor shower, that created a strange energy and mutated the beings of the earth. Such superficial knowledge was known to everyone, thought a vast number of people still deny its claim.
After the cataclysm, the civilization almost had to start from scratch. However, they progressed much more rapidly than the previous civilization, quickly crossing the era of feudalism and arriving into the modern era.
However, what was hidden from the public, was the origin of meteor shower and the monstrous beings.

Both dimensions overlapped on each other perfectly, but thick enough to make no one notice at all.
