Prebeings

Prebeings are four omnipotent godlike entities of unknown origin, responsible for recreating the universe after its death.

Appearance
They posess no true form, or at least none that mortals would fathom. Most of the time they manifest themselves as a mass of light of varying size and color.

Powers and abilities
They are omnipotent, omnipresent and omniscient, so they are beyond almost any limit ("The Fiction" being the only exception - them being fictional automatically makes them inferior to anything existing in real life), capable of rewriting and freely controlling time and space. They however, do not use their abilities unless the fate of the universe is at stake.

Role in Nocandian History
Aside from their role in rebuilding the universe, they didn't intervene in any event that took place since, choosing to passively observe them.
