The Higher Realms are the dimensional plains of existence that lie outside of the three dimensional multiverse. While in that plain the entireties of physics, energy, time and power differ, the Higher realms reside any and all known forces and are home to various god-like beings that call it home.
The Phoenix Realm is a virtual existence outside the bounds of the tangible universes and physics of the multiverse; beyond the area of normal, sub and hyperspace and even against worlds that claim their physics are non-existent. This realm is developed by Pyre with the combined efforts of the other four sorceresses to act as a nexus from the modern universe to other multiverses out there. It is also known for its famed inhabitants that are known all around in legend to full existence: Phoenixes.
The Sole inhabitants of this realm roam freely within and outside of the tangible planes and are powerful beyond their means but peaceful and bound to never interfere [too much] but to watch and interact with the universes around them, Most of them are known to be guardians, others to be the normal groups of species within a planet and often but rarely are souls who arrived after their deaths. Often it's ultra rare that these kinds arrived at the phoenix realm. There are three main types of phoenixes that dominate this existence: Natives, Guardians and Spirits.
- Native Phoenixes are the ones who are born, raised and live in the boundaries of the realm and live happily among their own kind without prejudice but they do fought in wars and minor hostilities but that is where the Guardians control.
- Great Guardian Phoenixes are the will-learned and protective species that are there to protect the realm and both the natives and spirits along with special abilities like enhanced strength, nigh-invulnerability, and freedom from fate and physical limits of any universe to protect other universes, and stop renegade phoenixes from destroying lives.
- Spirit Phoenixes come in two kinds: the delivered and the guardian types. They are made from the souls and/or life energies of various species who died prior to adsorbing the feather of a guardian phoenix which are ultra rare to find in any universe. Spirits can become Guardians with the ability to come back to their native universes even to be 'resurrected' but in the process they become smarter, stronger and faster than ever before because of their abilities.
Time differs in the phoenix continuum as time doesn't exist unless wanted to. Though a lifetime the inhabitants don't go though the typical burnout and are eternal all the way. Should a spirit or a guardian makes it through, over billions or even trillions of years may passed that is why they have that ability to go back.
