The realms of Myst stretch far into the universe. At night, when the Sun's blinding light has faded, you can see the constellations of the outer worlds in the heavens. But Myrth is a place of flux, where the nature of the cosmos is most profound. It stands as the pinnacle, a anchor of sorts, at the centre. And its Great World Trees bind all of creation to it.
The nature of the universe, the Myst, and Magic is balance. Without the balance, there is no cosmos. And Myrth, the prime Plane of Existence and Substance, is the scale responsible for that balance.
Many cosmic planes exist beyond, and a number of them inside, or parallel to the Material realm. These are categorized into groups, depending on their nature.
Transient Planes
Beneath, parallel, universal, encompassing. The link between the tangible realms require a "vessel" or sorts, or rather, a "glue" that binds these places together. As soap bubbles cling together on the surface, forming an absolute, yet fragile and shifting boundary.
These planes exist in parallel to the Material realm and to some extent form part of it. They connect through the roots of the World trees and as such, the borders between them are often blurred.
Known Echo Realms
Tartarus: The parallel battlegrounds of Law and Chaos. Also known as Limbo or The Barrier
Elysium: The core of the world, the primal source of its mystical powers. The place where the essences of life rests. Also known as The Soul Forge
Gaia: The heart of the world, where the primordial essence of nature is bound
Heldar: Heldar is the celestial plane of the Dwarves
The Inner Circle groups together the planes in close cosmic proximity to Myrth and the Material Realm. They tend to influence Myrth to some degree due to this proximity.
Known Inner Circle Planes
Aegis: The Silver Moon. Pinnacle of Law and Order and the home of Lawful Outsiders
Nox: The Crimson Moon. Pinnacle of Chaos and Destruction and the home of Chaotic Outsiders
Ordania: The Floating Castle of Selflessness and Justice, circling the Sun and home to the Divine Law-bringers
Crevatorus: The Scattered Debris of The Void Seed, filled with deep holes and gateways to the Abyss
Outer Circle
The Outer Circle groups together the planes that are spread far from Myrth. They form the constellations of the night sky and serve as beacons to the single principles or portfolios held by the Divines.
Known Outer Circle Planes
Ruune (The Crown): the vault of Maia, filled with starlight of gold.
Shole (The Phoenix): the fiery sky world of Armara
Umber (The Emerald Lion): the Three-sun vigil, claimed by Lord Aster
Onus (The Southern Chalice): the barren land where the spirit of Erthan has its final rest after the apocalypse
Kesra (The Great Tree): the sprouting root world of the Great Trees amd gateway to the Far Realms, claimed by Opus
Kelon (The Fractured Wheel): the sanctuary where Ornim
Eskall (The Anvil): the plane of everlasting cosmic storms, guarded by Tor
Far Realms
Beyond the boundaries of space and time is a place that is not a place, called the Far Realms. Few divines have ventured close to its borders and even less have returned unscathed. It is a place of even greater secrecy than the knowledge of creation.
Known Far Realms
Hole to the Void: A deep, black hole at the edge of space and time. What lies on the other side is unknown
