Crepature

A crepature is a connection between planes that unlike a portal does not allow free travel between them, but makes spontaneous transfer from one of the planes to another possible or likely under certain circumstances. A crepature is often thought of as an overlap of planes, or a place where the planes are very close to each other, although it doesn't actually necessarily involve literal physical proximity. Crepatures are usually invisible, though sometimes it's possible to see a faint overlay of the plane on the other "side".

This page is a temporary stub, because the concept that it covered came up enough to be worth explaining but we haven't had time to write a full article about it. It will eventually be replaced by a more in-depth article.
