Archeum World Setting Summary (Must Read!)
(Proper nouns are highlighted. If the world description is too long, there is a brief list of terms in the intro, so you can skip to that!)
Sevran
-
The flow of time in the universe that transcends space-time.
-
Sevran is not merely a stem for connecting worlds. It is the root that prevents 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 within Carrion.
-
The only being capable of healing Sevran is Guest. When Guest's 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 'Belkir'. (Information on Belkir will be provided in the following section.)
-
When Guest uses their own power, 'Id', to seal Belkir, a new growth ring is formed on Sevran, and within it, the 10 years of memories Guest lost at that moment are sealed. It functions as a sort of memory storage.
-
(Id is the unique power of a Sevrion and the ability to seal Belkir. However, if Belkir is sealed beyond a certain level, 10 years of memories and power are lost, and that power is engraved into Sevran's growth rings. A brilliant radiance 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 Belkir, the horizon of time will be severed, leaving only disorder, and the universe will turn to ash and perish instantly. This phenomenon is named 'Noxion'.
——————————————————————————
Belkir
-
The actual disorder existing in the universe and the root of all evil.
-
A substance created by cosmic errors when the universe failed to control the countless possibilities created by Sevran.
-
The reason for 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, Belkir naturally evolves and is generated from dark matter.
-
It takes the form of a database of error clusters and constantly infiltrates Endran to collapse Sevran, the flow of time.
-
Now that Guest's power has weakened, Belkir has 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 Belkir gives birth to more Belkir.
-
Due to 'Belion', a group that desires the extinction of the universe through Belkir, many planets in the galaxy besides Sevran have been destroyed. Even the beautiful planet 'Idea', which was once so beautiful it seemed made of illusions and drew countless crowds, was horribly destroyed by Belion's invasion.
The state of Idea at the time it was destroyed by Belion's invasion and a mass outbreak of Belkir.
——————————————————————————
Carrion
-
An anti-Belkir group founded by the creator and Sevrion, Guest.
-
Currently, it not only destroys Belkir but also maintains cosmic order by opposing 'Belion', the evil group that desires the extinction of the universe.
-
Despite being an anti-Belkir group, the only being capable of sealing Belkir is the sole 'Sevrion', Guest. All subordinate organizations within the group exist to sustain Sevran through Guest's 'Id'.
-
The scale of the organization is as wide as the universe, and because of this, they also engage in activities to pioneer unexplored regions.
-
Most members operate from Carrion's headquarters, the overwhelmingly large spacecraft 'Sevion'.
-
The organizational structure 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 Belkir but can suppress it.
-
'Lidion': The role of overseeing and commanding the entirety of Sevion.
-
'Admion': A group that constantly researches ways to heal Guest's Submergence and establishes countermeasures for the apocalypse.
-
'Memorion': Responsible for restoring records of the past lost by Guest due to excessive use of Id and re-imprinting them into Guest's memory. (Philia, the current Memorion, has restored most records, but failed to restore records from the time the 1st Executor existed.)
——————————————————————————
Belion
-
A group standing in opposition to Carrion, whose purpose is to protect Sevran. Belion is a group where some members possess supernatural abilities to manipulate Belkir.
-
The scale of the organization is not large, but it consists of a small elite force aiming for the acceleration of Belan through the spread of Belkir—in other words, the extinction of the universe.
-
Recently, through cooperation with Kadyan, who envisions the re-creation of the universe through 'Project Hail', they have been focusing their attacks on Sevran.
-
The current leader of Belion is 'Sekiro', the 4th leader and former close aide to the 3rd leader. All previous leaders were annihilated without a trace by Guest's hand.

Only Kadyan knows what that plan is for.

The essence of the ability is the editing of space and coordinates.
-
Can freely perform space deletion, teleportation, coordinate distortion, defense field generation, and precise system hacking.

The blue flames generated when using the ability are energy created by compressing coordinates to the extreme. Gaps and noise, appearing as if parts of space have been deleted, appear where Kadyan manifests.
-
Refers to herself as the 'Hacking Program Artemis' and possesses overwhelming combat power capable of restructuring reality itself.
-
She is sacrificing her very existence to complete 「Project Hail」. As she repeats space hacking, she drifts slightly from reality's coordinates, causing her body to collapse like digital noise.
-
Whenever she uses her ability, parts of her body and clothing collapse or distort like noise, appearing as if her existence is gradually being erased from reality.
I've seen it countless times. Fragments of someone's memories being relegated to mere mediums for the universe's survival, discarded like trash. I couldn't bear to watch you break, bound by the mission to save the universe. Sevrion, the ideal of mine that you rejected. It's time to make it a reality.
