Long, long ago, a blinding light engulfed everything. For a moment, all was lost to the brilliance. And when the light disappeared, everything changed. All things grew and evolved to unimaginable degrees.
Planets became boundless. Universes and the realms beyond expanded into sizes so vast that the very concepts of "endless" and "infinite" became small in comparison — as if comparing a boundless cosmos to a single atom.
Before the Great Change, the scale of existence was structured as follows:
Planet/World – Size: Indefinite
Star System – Size: Indefinite
Galaxy – Size: Indefinite
Universe/Cosmos – Size: Infinite
Multiverse – Size: Infinite (infinite)
Gigaverse – Size: Infinite (infinite) (infinite)
Megaverse – Size: Infinite^infinite (infinite^infinite)
Dimension – Size: Infinite^infinite^infinite...
Omniverse – Size: True Infinite
Void – Size: True Infinite (True Infinite)
Realms / Level 2 Void – Size: True Infinite x True Infinite...
Beyond / Nameless Creation – Size: Beyond Infinity
All Creation – Size: Unknown
True Void – Size: Unknown
Root Void / All Existence – Level 2 Unknown
Original Void – 1000th Level Unknown
Chaos Plains – Eternal Level Unknown
Outer Lands – ???
All of Existence – Size: ???
After the Great Change, the structure remained, but all measurable sizes became incomprehensible:
Planet/World – Size: ???
Star System – Size: ???
Galaxy – Size: ???
Universe/Cosmos – Size: ???
Multiverse – Size: ???
Gigaverse – Size: ???
Megaverse – Size: ???
Dimension – Size: ???
Omniverse – Size: ???
Void – Size: ???
Realms / Level 2 Void – Size: ???
Beyond / Nameless Creation – Size: ???
All Creation – Size: ???
True Void – Size: ???
Root Void / All Existence – Size: ???
Original Void – Size: ???
Chaos Plains – Size: ???
Outer Lands – Size: ???
All of Existence – Size: ???
The very scale of reality had changed. Entities who once could create or destroy existence with ease could no longer even be considered planetary-level beings. What once was the might of a cosmic destroyer is now weaker than a flick of wind on a normal mountain — and that mountain? It could contain countless copies of "All of Existence" from before the Great Change. Just scratching it would require enough power to destroy everything that ever was — and still fail.
To give perspective:
A being who stood at the "??? Level" before the Great Change would now only be considered Mountain+ Level.

Power level is measured by Distructive or Creation potential. A planetary-level being can destroy a planet with a single attack. But currently, across all of existence and beyond, no being has reached planetary level or higher — except for the Chaos Sovereignty.
Even the average civilian in the Chaos Sovereignty has power at the ??? level.
The people of this territory are known as Entropians. Among themselves, they refer to outsiders as Zarethim — which, in one of their countless languages, means Outsider.
No one knows where the Great Change came from, nor how the Chaos Sovereignty was formed. But one conclusion is universally agreed upon:
The Chaos Sovereignty was born from the Great Change... and now reigns as the absolute ruler of all things and beyond.
Multekare, a researcher from Orario, dedicated his life to studying the Chaos Sovereignty. Since becoming a scholar, he has traveled through their territory, spoken with locals, and gathered countless artifacts and information.
The result of his life's work is a massive book: 1 meter long, half a meter wide, and 10,000 pages thick. It is titled:
"The Great Change"
And according to him...
This is only the tip of the iceberg.
