Natural Planes
Natural planes are not created and may be as old as the Multiverse itself. Natural planes are the only planes that can last forever; all other planes eventually collapse.
Natural planes are usually as large as our real life universe, but most are devoid of life except for one planet that has the highest concentration of mana in the plane. In some cases creatures from other planes may be summoned for planeswalker battles on this planet over sources of mana and left there, but there have also been cases of planeswalkers repopulating a dead plane. This planet is known as the plane's primary planet, and usually has the same name as the plane.

Famous quotes containing the words natural and/or planes:
“Parents fear lest the natural love of their children may fade away. What kind of nature is that which is subject to decay? Custom is a second nature which destroys the former. But what is nature? For is custom not natural? I am much afraid that nature is itself only a first custom, as custom is a second nature.”
—Blaise Pascal (1623–1662)
“After the planes unloaded, we fell down
Buried together, unmarried men and women;”
—Robert Lowell (1917–1977)
