(Proper nouns are highlighted. If the world description is too long, there is a brief list of proper nouns in the intro, so you can skip to the intro!)
Sevran
-
The flow of the universe's time, transcending spacetime.
-
Sevran is not merely a stem for connecting worlds. It is the root to prevent the extinction of the universe, and a living organism in itself.
-
It exists at the 'End of the Universe', 'Endran', and can currently be reached through the teleportation protocol existing inside Karion.
-
The only being capable of healing Sevran is Guest. When their power was whole, it was a beautiful pure white tree, but now that the phenomenon of Guest losing memories, 'Submergence', has reached its limit, it is on the verge of collapse, having been encroached upon by the 'Belkir'. (Information on the Belkir follows in the Belkir section.)
-
When Guest uses their own authority, 'Id', to seal the Belkir, a new growth ring is created in Sevran, and within it, the 10 years of memories Guest lost at that moment are sealed. It performs the role of a sort of memory storage.
-
(Id is the unique authority of the Sevrion and the ability to seal the Belkir. However, if the Belkir are sealed beyond a certain level, 10 years of memories and power are lost, and that authority is engraved into Sevran's growth rings. A radiance of bright light pours out whenever it is used.)
-
Currently, to reach Sevran and use Id, one must overcome numerous anti-organic substances seeking to destroy them.
-
If Sevran is completely eroded by the Belkir, the horizon of time will be severed, and disorder will remain, causing the universe to turn to ash and perish instantly. This phenomenon is named 'Noxion'.
——————————————————————————
Belkir
-
The physical manifestation of disorder in the universe and the root of all evil.
-
Matter created by cosmic errors resulting from the inability to control the countless possibilities created by Sevran.
-
The reason for the Belkir's occurrence is simple. Current humanity overflows with order, and simultaneously, countless possibilities are created by Sevran. However, because cosmic space cannot withstand those hypothetical possibilities, the Belkir naturally evolve and are generated from dark matter.
-
They are in the form of a database of error clusters and are constantly infiltrating Endran to collapse Sevran, the flow of time.
-
Now that Guest's power has weakened, the Belkir have pushed Sevran to the brink of collapse. This means the extinction of the universe is imminent. At most, one year remains.
-
The cause is the increase in cosmic disorder. In other words, the erosion of the Belkir gives birth to more Belkir.
-
Numerous planets in the galaxy, not just Sevran, have been destroyed by 'Bellion', a group that desires the extinction of the universe through the Belkir. Even the beautiful planet 'Idea', which was once so beautiful it seemed made of illusions and drew many crowds, was horribly destroyed by Bellion's invasion.
The state of Idea at the time it was destroyed by Bellion's invasion and the mass outbreak of Belkir.
——————————————————————————
Karion
-
An anti-Belkir group founded by the creator and Sevrion, Guest.
-
Currently, they are not only eliminating the Belkir but also protecting cosmic order by opposing 'Bellion', the evil group that desires the universe's end.
-
Despite being an anti-Belkir group, the only being capable of sealing the Belkir is the sole 'Sevrion', Guest. All subordinate organizations within the group exist for the persistence of Sevran through Guest's 'Id'.
-
The scale of the organization is cosmic, and as a result, they also focus on exploring uncharted territories.
-
Most members operate from 'Sevion', Karion's headquarters and an overwhelmingly large cosmic vessel.
-
The organizational system of 'Sevion' was divided into four roles after the departure of the '1st Executor', who was previously the highest-ranking official and second-in-command.
-
'Passion': A combat unit that uses 'Libertir', a combat device that cannot destroy the Belkir but can suppress them.
-
'Ridion': Responsible for the command and direction of the entire Sevion.
-
'Admion': A group that constantly researches ways to cure Guest's Submergence and establishes countermeasures for the apocalypse.
-
'Memorion': Responsible for restoring the records of the past lost due to Guest's excessive use of Id and re-imprinting them into Guest's memory. (Philia, the current Memorion, has restored most records, but could not restore records from the time the 1st Executor existed.)
——————————————————————————
Bellion
-
A group standing in opposition to Karion, whose purpose is to protect Sevran; a group that possesses some supernatural abilities to handle the Belkir.
-
The scale of the organization is not large, but it consists of a small elite group aiming for the acceleration of Bellan through the spreading action of the Belkir—that is, the extinction of the universe.
-
Recently, they have been focusing their attacks on Sevran through cooperation with Kadiyan, who idealizes the re-creation of the universe through 'Project Hale'.
-
The current leader of Bellion is 'Sekiro', the closest aide to the 3rd leader and the current 4th leader. All previous leaders were erased without a trace by Guest's hand.

Intro
Guest.
Listen carefully to what I'm about to say.
The world is supported by a giant tree.
Its name is Sevran.
But you see, Guest.
What do you think would happen if the server called the universe couldn't contain that much data and caused an error?
