Here's more lore about Servant Universe, Godess Concept ,SIshtar,Ether Universe ...etc.
It's gonna be a long one :
Goddess Scriptures 1: Origin of the Ether Universe:
here is a proper use of the word ‘galaxy’.
The galaxy in which we humans… in which people live in, is called the [Milky Way Galaxy], whereas other galaxies are simply called [galaxies].
The same rules of nomenclature should apply for your universe.
The [Milky Way], in other words, the milky river of heaven, and [galaxies] refer to the other rivers besides it.
In other words, in the Servant Universe, the [Milky Way] is called the [Ether Galaxy].
However, the [Ether Galaxy] was called a different name in the far past.
That name remains unknown.
After all, the [Renewal of the Universe] overwrote everything.
What is the [Renewal of the Universe]? To put it in simple terms, it would be the updating of the universe.
Humans, which had lived thus far in their [bodies of flesh], discarded their bodies one day---
For soul vessels, [Saint Graphs], changing their own way of being. They were released from their limited mortal lives, from their limited ability.
[Humans] disappeared from this Milky Way, and everyone became [Servants].
Hm? Then [mere humans] who aren’t Servants no longer exist, you might ask?
Well, they haven’t all disappeared. In fact, they became far more important.
After all, only [humans] can become [Masters].
Well, let’s leave this topic for another time.
Anyway, Servants became the only form of humanity in the [Ether Galaxy].
As Servants are souls taking physical form, naturally, the universe would require a correspondingly large amount of energy.
Therefore, as a result of all humanity becoming Servants, the universe was filled with Ether.
Here, in space, the [Ether Galaxy] contains various substances.
Besides the cosmic dust present in your universe, there is Ether, Artorium, Eliza, Gudaguda, Kykeon, Sakura, Velber…
Various such particles have been discovered. Of course, they will continue to increase from now on.
The [Ether Galaxy] is a universe filled with possibility and chaos. A new universe where myriad “ifs” can be lined up side by side.
However, that was not the case for the old universe.
It was an era where humanity was mostly [human]… where [God] was in space.
That is what we call the [Universe of Origin], the universe of the beginning.
It is still unclear why the [Universe of Origin] was permitted to be rewritten into the [Ether Galaxy].
But, it all happened 5 billion years ago.
Humanity has prospered in the [Ether Galaxy] only for the last 500,000 years…
Indeed, there is a discontinuity of 4.9 billion, 9 thousand, 9 hundred and 50 million years. There are far too few records of the [Universe of Origin].
5 billion years is an unimaginably long span of time for humanity.
But for space… no, for [God], it may feel like the “recent past”.
Thus---
Should a remnant of the [Universe of Origin] still exist in the [Ether Galaxy], beware.
That would be someone who stood at the apex of an ancient civilization which far predates us, someone who hates our evolution, as if it only happened yesterday.
