Celestials

Celestials are a race of entities that are the Immaterial Counterparts of celestial objects like moons, planets, stars, galaxies, and even realities. They are the most powerful beings in the Nijisanji multiverse and are even considered the gods of said universe. Celestials do not exist within the Human Reality (with the possible exception of the Moon). They are also the source of all magic within the Nijisanji multiverse.

## Mechanics

As celestial objects are formed, large amounts of Immaterial Essence comes together tied to all the physical matter accreting to generate the celestial object. As this happens, complex interactions begin to happen between all the immaterial essence of the object. Given the informational nature behind immaterial essence, these interactions, when in large enough amounts and after a large amount of time (on celestial scales with Earth's moon being on the smaller end where this is possible), can result in the totality of the immaterial essence of the celestial object (its immaterial counterpart) becoming a neural network. Once this happens, the celestial object has reached sentience and a full Celestial is born.

Celestials can be connected and tied together. Celestial essences can be shared, for instance between a star and its planets given they formed from the same materials. A supernova of a celestial seeding a new solar system can seed that new solar system with some of the essence of that deceased celestial. On the most grand of scales, galaxy celestials are beings which contain the entirety of the essence of all stars and other celestial objects within them. While each moon, planet, and star in the galaxy operates as their own independent entity, they are ultimately all interconnected into an even grander consciousness that is the entire galactic celestial. In the same way, all celestials in the entire universe are connected together into the Universe Celestial.

## Avatars and Humanoids

Celestial Avatars are the representations of entire celestial objects on smaller scales. They can move independently of the celestial object they are the immaterial counterpart of so long as every particle in their body is tied to every particle in the celestial object (which, due to nonlocality, can happen far across space). Avatars naturally assume a humanoid form, although the choice of the form to take is ultimately up to that celestial.

Because Avatars are humanoid, a lot of life across the galaxy ultimately takes on humanoid form. As evolution progresses, since all life on a planet is ultimately part of that planet (since the Immaterial Essence of all life on a planet is part of that planet's immaterial essence), the planet can guide the progress of evolution on itself. This often leads to evolution leading to a form which resembles the Avatar itself given the Avatar is putting more and more of itself (and thus its own image) into its own life. This is why humans are so prevalent and in general why humanoid forms are so recurrent.

## Magic

All life in the universe is part of some celestial, the celestial they were born on. This is because all atoms and particles within their body are ultimately tied to immaterial essence derived from that planet, and thus are a part of that planet's Avatar. In most cases, all matter has equal density of immaterial essence, but if a celestial desires it, they can "bless" an entity with more of its own essence, increasing the density of immaterial essence within that individual entity. This allows the entity the ability to control the flow of immaterial essence in different ways, leading to them being able to use magic!

Celestials without the ability to evolve life directly can also bud to procreate, creating entire new races of life in the process in their own image. Celestials and powerful buds can even create new Immaterial Essence through the process of particle creation which happens at high energies.
