THE OUTER PLANES

The Outer Planes only appear as a ring when they are drawn on a paper sheet. On paper Ysgard is sketched next to Limbo, but it doesn't mean that a planewalker can just pass through some phisical boundary between the two planes. The planes are virtually infinite and don't lay out like countries on a map. They are organized according to outlook, good versus evil, law versus chaos. Most primes divide the planes in "good" and "evil" ones; the good ("Upper") planes are: Arcadia, Mount Celestia, Bytopia, Elysium, the Beastlands, Arborea and Ysgard; the evil ("Lower") planes are: Acheron, Baator, Gehenna, the Gray Waste, Carceri, the Abyss and Pandemonium. Mechanus and Limbo are the planes of purest law and chaos.
Many planewalkers consider more important another way to dissect the Great Ring: by the planes orientation towards law and chaos. Between the planes of law and chaos there are the planes of conflict, where neither extreme law or extreme chaos prevail, they are the planes of neutrality.
