Celestia is a mysterious location that very few people understand. It is the floating island that can be seen in the sky above Teyvat, and the residence of the gods.
It is said that only mortals who perform great, heroic feats can ascend to Celestia and achieve godhood, where they will watch over their people from above. A human with a Vision is an allogene — one with the potential to reach godhood.
The floating "island" actually seems comprised of several landmasses, with one large central rock and about seven to eight smaller "satellites" positioned around it. These outer rocks are connected with one single ring-like structure which again is held in place with several bridges or arches expanding from the central mass.
All of these foundation rocks appear almost as if torn from the earth at some point in the past, with their surfaces covered in lush plains and forests contrasting the rough, craggy undersides. While a few signs of architecture are visible on the outer rocks, the main focus lies on the central mass, with two discernible structures made out of marble or similar white stone. The first is a smaller spire-topped structure positioned on the rim of the central mass, while the second is the more prominent central multi-storied spire which itself is topped by a massive golden construct, reminiscent of an astrolabe.
Additionally, the architecture of the central mass seems to descend deep below the surface level with a distinct inverted dome peeking out from the very bottom of the rock.
Apart from the mentioned forests and green plains on the upper surfaces of the land masses, it also appears to have several subterranean rivers bursting forth from the rock, gradually diminishing into nothing during their free fall of hundreds of miles from above the ground.
While the overall appearance is still imposing and breathtaking, even at a distance, slight traces of disrepair and wear are noticeable among the bright marble structures with broken-off pieces on the spires and bridges.
Position in the Sky
Celestia does not move in the sky like the moon or sun, but the view changes depending on where it is viewed from. From Stormterror's Lair it is almost horizontal, but from Qingyun peak it appears heavily tilted.
Relationship to Teyvat
In other, distant worlds...
Pangu gave his blood to form the rivers and seas...
The gods sacrificed Purusha and cut his body to pieces...
...And then fashioned all living beings with those parts.
The brain of the giant Ymir became clouds.
Their sacrifices seeded life in the unliving cosmos.
These songs sing of the primeval ones.
Celestia and those who dwell on it are an enigma to the people of Teyvat. Most people believe it is where chosen mortals ascend to become gods (or in Liyue belief, adepti) and watch over those on Teyvat.
Due to the amount of mystery surrounding this island, different accounts about how Celestia operates, and who qualifies for godhood and how, vary significantly. For example, some believe that adepti descended from Celestia and return there when they depart from this world; whilst other sources believe that Guhua, an adeptus, ascended to Celestia instead of dying.
When speaking about Vennessa, the Falcon of the West of the Four Winds who supposedly ascended to Celestia, Dainsleif claims "it ultimately does naught but hover under the light of the gods," suggesting that even those who ascend to godhood are still considered beneath the Celestial gods, and not as equals.
In the distant past, humans were able to communicate with Celestia directly through heavenly messengers. The ancient civilization of Sal Vindagnyr was one such example, based on the Mural Room. For reasons unknown, Sal Vindagnyr was eventually destroyed by Celestia itself when they dropped the Skyfrost Nail, destroying the nation's Irminsul tree and shrouding the region with unrelenting blizzards. Their heavenly messenger no longer responded to them, and their head priest's attempt to find answers ended in vain.
Relationship to the Archons
The Seven Archons are said to resonate with the power of Celestia directly through their Gnosis. They, and other gods in the world of Teyvat, have a connection to Celestia but remain silent on the subject themselves. Dr. Edith surmises that only mortals who have ascended to Celestia due to their achievements can tell its story.
So far, the Archons seem to have a tenuous relationship to Celestia at best. Venti constantly avoids the subject, giving cryptic responses whenever asked and growing visibly uncomfortable whenever it is brought up in the manga. In the Teyvat Chapter Storyline Trailer, Dainsleif says that the Hydro Archon (the God of Justice) "knows not to make an enemy of the divine," while the Tsaritsa is planning a "rebellion against the divine" — which may be why she seeks to take the other Archons' Gnoses.
According to Soraya, the Archon War was fought over who would take each of the seven divine seats at Celestia. However, it is currently unknown what caused the formerly peaceful coexistences between gods to dissolve so quickly, or how these seven seats were created to begin with.
The Heavenly Principles
Celestia appears to either control or act under the "heavenly principles" (Chinese: 天理 "heavenly principles, natural order"), also translated as "destiny" or "the divine." When the Unknown God confronts the Traveler and their sibling, she calls herself the "sustainer of heavenly principles" (Chinese: 天理的维系者). These heavenly principles are also intricately linked to the "truth of this world."
The driving conflict in the Teyvat Chapter is the role of the heavenly principles during the cataclysm 500 years ago. The ancient kingdom of Khaenri'ah was destroyed in an attack led by Celestia and The Seven, apparently in accordance to destiny (the heavenly principles). After the kingdom fell, its people were cursed; Dainsleif was cursed to wander the world as an immortal being, while many of the people became monsters. These monsters banded together to become the Abyss Order, which seeks to topple the divine thrones and destroy Teyvat. The hilichurl tribe known as the Eclipse Tribe also seems to have some relation to Khaenri'ah, sharing its name with the kingdom's Eclipse Dynasty.
Celestia's actions during the cataclysm came at the consternation of several of The Seven themselves. Tsaritsa formed the Fatui to challenge the "foundational principles of the world" and rebel against "the divine." As part of her plan, she has been conspiring to take all the Gnoses, through force or otherwise. Zhongli willingly surrendered his Gnosis after the people of Liyue passed his test to see whether they could survive without a god, tacitly granting his approval of her goal.
- In Gnosticism, above the seven heavens (worlds) presided over by the seven archons is the Ogdoad, a supercelestial region which mortals aspire to reach through gnosis.
- Celestia and its gods may also be inspired by the Demiurge who, in Gnostic beliefs, fashioned and maintains the material universe; he created the seven heavens and created the seven archons to rule over them. The Demiurge himself is the son of Sophia, one of the aspects of Pleroma, but is ignorant of an even-higher existence and thus came to believe himself to be the one and only god. In some Gnostic beliefs, the Demiurge is an antagonistic figure that seeks to prevent mortals from leaving the material universe and ascending to Ogdoad via gnosis.
- When Venti dodges The Traveler's question about whether those who ascend to Celestia truly become gods, the names he mentions — Pangu, Purusha, and Ymir — are names of mythological figures connected to creation myths. A common thread between these three figures is that after their deaths, their body parts were scattered to create the world.
