Yume
夢
Yume (yoo-meh) is a world in constant change. Its very nature swings back and forth between light and dark. It is populated by people of all shapes and sizes that are all interconnected with their world—a supra-massive city that climbs a tree the size of a moon.
A World of Light and Dark
Yume is a moon that orbits a giant water planet, Leviathan, which in turn orbits the Crystal of Arva directly. The number of fellow planets is unknown to Yumians. Yume was created as a hollow hemisphere whose inner surface is covered by land, sea, and sky. Floating at its center is a single, super-massive, tree–whose trunk and roots descend down close to the crust of the world, while it’s highest canopies extend over the rim of the half-sphere. Yumians call this world tree Shinju (神樹)
The Spiritual Plane
The entire realm shifts between Seikai ( the Material Plane) to Kōkai (the Dream Realm) every 12 hours. This is entirely normal for Yumians and they see very little difference between this dimensional shift and the shift between night and day.
Mythos
Long, long ago, when the world was still young, Shinju, the World Tree, rose from the void.
And upon its towering crown, the Nimbus was set, radiant and eternal.
むかしむかし、世界がまだ若かった頃、神樹は虚無から立ち上がった。
そしてその頂に、光楽園が輝きながら永遠に置かれた。
Before the heavens collapsed, the Nimbus (光楽園) was created for both spirits and people to dwell in peace. This large ringed structure that floats in the upper canopies of the great Shinju was, and still is, a beautiful sight to behold. Then, after the stars rained down, and the world was split in two, humanity decided that it would not be good that everyone should be allowed to gaze upon the highest canopies of Shinju—the last place the great spirits were seen walking amongst humanity.
And so many were cast down from the canopies, and the city of Yume was split in two—those the lived in the Nimbus, and those that lived in the Lower End. Only those who are highly devoted, and their descendants, are able to live in the paradise and away from the stagnant life of the lower city.
Life in the City
Politics Governance in Nimbus is overseen by the Shinsei Council (神聖会議), a theocratic technocracy composed of six Elders and one Tenshō (Heavenly Light), a quasi-divine figure elected once every century through a ritual known as The Calling of...
Seasonal Cycle
Yume has a full 24 hour night/day cycle, and each 24 hours is split into 6 hour "seasons". Summer During "Summer" Yume is fully in the Kōkai (光界 ・こうかい (literal meaning is “Yang Realm” - like yang/light/positive energy - also reads as "spirits" so has dual meaning)....
The City of Yume
The eponymous supra-city of Yume is split in two sections, the Nimbus which rings the canopy of the world tree, and Ne-no-Mori which straddles the lower trunks. Ne-no-Mori also descends far down into the rising waters, the city itself climbing up the tree over...
