1. Could explain the essents more
2 is it just the ones you’ve listed or would say tikki and vitaa or shii and tikki be able to merge for example. Like can any alpha Kwami merge with any other alpha Kwami?
Okay long post time! There's a TL;DR at the bottom because... long. xD
So, there are three levels of entities that make up the universe. The first is a Transcendent, who can then further divide into Essents, who from there can divide into Kwamis. Kwamis can either split their concept further into more kwamis, or can create new Kwamis that are aspects of their concepts without further dividing. Each level of division creates a being whose concept/domain/embodiment is more intricate than what came before.
The one and only Transcendent is a being that the kwamis call Omnii, who embodies the Universe as a whole. Omnii did not have a name in its time, as Omni did not have a conscious or a sense of self. At this point Memories, Psyche, or even Time did not exist. Kwamis themselves barely understand the full concept of Omnii, and have more of a vague awareness that it once existed.
Omnii divided and reformed many times when it was, and this was when Essents came to be. Like Omnii, at this point Essents did not have any sense of self. There were just vast forces of raw power and energy. Essents embody very vast domains, which often changed depending on how Omnii divided its form. At times it was divided into Negative and Positive energy, other times it became things that embodied other aspects. Being and Matter. Existence, Reality, Balance, Infinity. Sometimes it would only divide a part from itself, creating an Essent that could not remain for long. All that came with these Essents were never stable, and it always collapsed back into Omnii.
This changed when the Essents themselves divided, creating beings that represented more fine concepts; which is what created the Kwamis. The Essents themselves were too vast, but by dividing further they created two opposite forces that were once one Essent. Forces of a whole that could act on their own, and create a stability that wasn't there before.
From Existence came Life and Death. From Reality came Creation and Destruction. From Balance came Order and Chaos. From Infinity came Space and Void. And from them came the foundation of the known universe, this splitting of the Essents into Kwamis creating the event that humans would came to call the Big Bang.
Omnii at one point split into Positive and Negative energy Essents, but they were not stable. Instead it split into Essents that encompassed both of this energies (these being Existence, Reality, Balance, and Infinity), and then when they divided they split into more refined concepts with one made from pure negative and one pure positive energy, each of these halves creating the Alpha Duos.
This splitting however resulted with a release of pure neutral energy spreading out into the universe, which formed the youngest Essent, Leebra, Essent of Neutral Energy. Like other Essents however Leebra was not stable, and soon divided into Kwamis as well. Kwamis like Eeterna, the Kwami of Time; and Uunice Kwami of Magic; Leebra becoming all of the Elemental Kwamis.
At this point only the Alpha Kwamis and Elemental Kwamis existed in the universe, and like the Essents that came before them they were raw forces of power and not individual beings with thoughts and personalities. They too did not have their names at this point, as these would come billions of years later.
The only Kwami with any form of awareness at this point would be Eeterna, the Elemental Kwami of Time. They did not have an awareness of self or anything like the life seen in the universe today, but Eeterna embodied all aspects of Time. It was likely every single moment ever to exist in the universe was their reality all at once, meaning this being had a full awareness of all that would happen in existence. Because of this they were... aware, for lack of a better word, that the Kwami of Time would not exist for long. So like the Essents they came from Eeterna too divided (being the only kwami to do so), creating all the Timekeepers, who embody finer aspects of Time.
From this point on the universe, and thus the Kwamis themselves, became more complex. These kwamis however, did not divide like Eeterna or Essents, but new concepts were still being formed as the universe grew, and thus new forces for these concepts came into existence. Instead of being new beings divided from higher ones, they were beings that branched off from the Alphas Kwamis. The Alphas still existed, but had finer aspects of their domain representing these new concepts, thus creating the Delta Kwamis. And of course as new concepts came, so did traits like individuality and consciousness, leading to the kwamis we know today. Delta kwamis can also have younger kwamis be branches of their concepts (like the Kwamis of Love, Sorrow, Hope, etc being aspects of the Kwami of Emotion, who is an aspect of the kwami of Life).
While when Essents first existed they had no consciousness of any kind, they have been able to experience awareness when the Alpha kwamis do merge together, by drawing on the memories of the kwamis that merged. This leads to a strange instance where Essents are technically the older and more powerful being, but act much younger and more naive of living with such a complex understanding as they've spent little time in this state. And they cannot spend much time like this, as they are still very unstable compared to kwamis and can only stay merged for a limited amount of time.
In theory any Alpha kwami can merge with any Alpha, but its vary rare that they do so outside of their Alpha Duo. The most common mergance outside of the Duo would be with Alphas of the same energy as them. The only combos that will get names are Alpha Duos merging, all Alphas of the same energy merging, and I also do have names for the physical Alpha Duos (Creation, Destruction, Space, and Void) merging along the spiritual Alpha Duos (Life, Death, Order, Chaos), but honestly I don't think those mergences will have any role in this AU story wise or lore wise. (If you are curious though their names are Ress the Essent of Matter for the Alphas that embody physical aspects and then Ibbi the Essent of Being for the Alphas that embody spiritual aspects.)
The only other kwamis that can merge are the Elementals, but only with each other and if all the Elementals are there... which they aren't because Eeterna divided into the Timekeepers. It is currently unknown if the Timekeepers can undergo a mergence themselves to become Eeterna again, since Eeterna was a kwami and not an Essent, and therefore a stable being.
TL;DR: A Transcendent named Omnii kept dividing into beings called Essents were who unstable and would collapse back into Omnii. One day four of the Essents divided into the Alpha Kwamis, who were stable beings that created the Big Bang and one more Essent who divided into the Elemental kwamis. One Elemental of Time divided into the Timekeepers, then new kwamis started popping up as the universe grew giving us the Delta Kwamis.
