Plane/Storyline

There are almost infinite planes in the multiverse, separated from each other by the space known as the Blind Eternities, which is filled with chaotic energies, including Aether and mana. The inhabitants of most of these planes have no idea that theirs is not the only universe, or indeed the only worldgenerally only planeswalkers know that and can travel intentionally between planes.
==Description==
Although Planes are sometimes thought to be a separate world occupying the same universe as other planes, each plane is a separate universe in its own right. Each has its sun and a few planes have multiple worlds, possibly with some inhabitable ones. Except artificial planes, most if not all planes can be considered more akin to alternate realities, with Dominaria - previously the center of Multiverse - being the prime reality. However, these realities are usually very different from each other, suggesting that planeswalkers cannot planeswalk between planes that are too similar.
Planes are known to "move" about each other. Additionally, new planes are constantly created, while others drift out of existence.Lynn Abbey. (1998). Planeswalker, ISBN-13 978-0786911820, Wizards of the Coast. According to Vivien Reid, each has a different starry sky. Sometimes the stars are colored like a rainbow. Sometimes they move, every night, as though they were giant fireflies.Django Wexler (2020), "Ikoria: Lair of Behemoths — Sundered Bond", Wizards of the Coast The Ten Realms of Kaldheim are constantly shifting and moving around the World Tree and can even collide. Such an epic event is called a "doomskar" and causes earthquakes, destabilization, and chaos. The plane of Arcavios was also formed by a collision of two planes and still has two suns.
===Natural planes===
Natural planes are naturally occurring worlds that came into existence at some point.<c>Planar Genesis</c> Most known planes have one central, populated world, that the entire plane is typically named after. However, it is possible that in vast universes with billions of galaxies and stars, other populated worlds also exist.Brady Dommermuth. (August 16, 2007.)

====Worldsoul====
A Worldsoul is the aware essence of a plane. One can be hurt magically, or manifest itself in various forms. Some magical abilities such as those of Nissa Revane may allow communication with a plane's Worldsoul.
===Artificial planes===
There are also artificial planes, worlds created usually by planeswalkers by sheer will (e.g. Serra's Realm). The creator of such a world defines all of its rules. These planes are unstable and eventually collapse if there is nothing to sustain their existence (like a constant flow of mana, or technical means such as flowstone). These planes are most likely surrounded by an amount of real space that prevents them from being destroyed by the Blind Eternities. However, this pocket of space eventually wears out, after which the Blind Eternities destroy the plane.
===Pocket planes===
Pocket planes are small "blisters" or artificial constructs that are split off from regular planes. Examples are Agyrem, Metal Island, Urza's secret room in the Starfield Orb and possibly Zhalfir before its reemergence. Another example may be the "Eversaloon" of Thunder Junction.Flavor text for
