Sentient Genesis

Sentient Genesis (or just Genesis) is how Excellion and higher beings refer to the creator of reality. He is the creator of all of the artifacts of Genesis, the Regalia and the Sons/Heirs of Genesis.

The Sentient Genesis is both the birth of the world and the world itself, as it is composed of it's divisions and Genesis is the origin of the Rapture, the expression of possibility.

Background ~ The birth of the world
Before creating the world, Genesis created The Composer and defined Excellion as a preexisting conceptual entity that would come to exist proper at a later date. He also created the artifacts of Genesis.

The exact method is unknown, but Genesis split itself into body, soul and mind that are true in the "dream" that is the Rapture, and with this same "burst of creation" gave the Regalia to a few select Sons of Genesis.

Artifacts of Genesis
The artifacts of Genesis are tools and weapons belonging to Genesis himself, the exact number of them is unknown.

They are known to be overwhelmingly powerful when properly used and have special abilities and properties.

Sons of Genesis
Genesis created a special race of creatures directly created from himself, the most well-known creatures are Excellion Lucis Caelum and Shiro.

These were default beings, a creature that can be modified into any other, thus they became able to shapeshift.

The disappearance of the children
Sons of genesis have become exceedingly rare through the years, there were mainly two contributing factors.

They are still being created in every universe to this day but the number of them isn't nearly as much.

The call
It is pretty much unknown what happened but one regalia wielder managed to momentarily consume all of the sons of genesis at once, this wielder is already dead.

Regalia wielders survived this but the rest of the children didn't.

Blending
This is a natural phenomenon. If the entire world (including yourself) was to forget your existence or a key piece of you, it would be as if such thing never existed in the first place.

Some sons of genesis blended into their surroundings so much they themselves forgot they were unique, thus they became unable to become what the were again. Loosing all their racial perks indefinitely.

Even if they were remembered of this once their identity is lost its impossible to regain.

Regalia
The Mark of Regal Radiance (Regalia for short) is the symbol of Sentient Genesis's authority.

Those who wield this mark are named Heirs of Genesis and called "Royals", although this name is rarely utilized and instead they are instead "commonly" called Regalia Wielders. These wielders gain a ridiculous power boost and the ability to shapeshift into any form they desire along with immunity to aging. Regalias are also classified by types, but for now, only Excellion's knowledge Regalia is known.

Wielders
The known wielders of the Regalia are:

Excellion Lucis Caelum (Knowledge and another unknown)

The Second (Sealed and probably dead)

Kosmos Lucis Caelum (inherited from Female Excellion, unknown mark)

Shiro (unknown mark)

There were also two wielders (first and fourth) that became Excellion.
