Lord Zack's Planescape
Material Planes are natural worlds, where normal beings like plants, animals, and people live. The forces of the Fundamental Planes come together to form these planes and the powers of the Spiritual Planes are revered by the beings of these planes, and furthermore the spirits of living beings come from these realms and return to them after death.
Some material planes do not obey the same rules as others. Some are dominated by a particular element, like Niflheim, Muspellheim and Jinnalm. In some worlds magical forces are more or less powerful, the latter of which applies to Earth. The realm of Faerie is very magical and is governed by bizarre physical laws. There are also rumors of planes that are similar to certain Material Planes, but with the details altered slightly, perhaps being similar to a point in that planes past, or hypothetical future.
The inhabitants of Material Planes are often seen as rather provincial by inhabitants of other planes. They have a reputation as the Clueless, having only a small amount of knowledge of the planes, some or even most of it wrong, from they’re myths and folklore. On the other hand there have been times when the conventional planar wisdom has been proven wrong and the “Clueless” have been vindicated.
