I've been thinking of Neil Gaiman's The Endless characters from The Sandman comics of DC/Vertigo comics. I have thought of implementing something similar to them. They are older than gods and unkillable forces of nature, as their destruction would merely be the death of their "point of view", with another form soon rising to replace them completely.

I already have Chaos as the living embodiment of all chaotic elements of the universe. To put it simple, he is all chaos that is in existence. He is everywhere all at once, only choosing where to make his form visible. He finds joy in the pandemonium he causes or in the general discord of the universe. Power wise, he is an extreme level reality manipulator, and has been around since the dawn of time. I have been toying with calling him Pandemonium, or Pan for short.

The Archivist is another character I have, chronicles the stories of the universes. Thousands of books fill his library, each one telling different stories of different worlds. I am considering making him the embodiment of Order in the universe, my variation of Destiny from the Endless, where Chaos is Destruction.

The final character of the trio that I need to work on is the Reaper, also known as Death. He, or she is the most incomplete, currently just an idea.
