As for the Physical Realm, this place is like the intersection between the white and black squares of a chessboard. Light and darkness blend together. Resonating with the appearance of matter created the sun, moon, day and night,... Gradually the sky also appeared, then the sea and the lands...As everything becomes congruent, the Earth was formed. Thus the structure of the world was gradually established and stabilized for thousands of years until the first living entities were formed. Due to the nature of the Physical Realm, the beings on this plane are not aware that hidden deep within the physical body is the source of Aether. Because of that, the creatures living in The Earth develop and evolve according to the laws of nature. Then humans were also gradually born and became the most dominant being to rule The Earth, also known as Middle-earth.
