The Planewalker's Guide to the Planes (PWH)

__TOC__
: "You know there's more to reality than the place where you were born. You have a grasp of the true scope of things. You've heard the maddening winds of Pandemonium and seen the crystal waterfalls of Mount Celestia. You've walked the Great Road and witnessed the naked reality of the Inner Planes. You are a planewalker.
: "Planewalkers can hold their own in a fight with a baatezu, share the chant with a githyanki, and navigate their way through the diaphanous Blade Maze of Therores in the heart of Ocanthus. They are capable, hearty, intelligent, and knowledgeable. Planewalkers know their way around a fight, but they know when to avoid a scuffle as well.
: They're no strangers to magic, and they know which side of a sword-point to be on. The dark of subtlety in word and deed is not lost on them.
: "The planes are too big for anyone to know everything about them—and no true plane-walker ever claims to know everything about everything. The trick is to know a little about a lot. That's what keeps a planewalker out of the deadbook. The essence of the planewalker is knowing how to get from here to there, who to talk to, who to avoid, and what to do to stay one step ahead. Knowledge is power."

It's obvious that cutters can't go everywhere in the course of their planewalking careers. Still, planewalkers need to have a general sense of what's what and what's where. Bashers have to know the difference between Acheron and Arcadia to avoid getting lost—in every sense of the word.
The following information comes from the renowned planewalker, Tarsheva Longreach. She claims that it's all—or at least mostly—accurate. She does extend the caution, however, that things change quickly" on the planes, sometimes in major ways. Just because a body visited a town, realm, or even layer yesterday doesn't mean that it'll still be there today.
