Each plane of existence has its own properties—the natural laws of its universe.
Planar traits are broken down into a number of general areas.
All planes have the following kinds of traits.
Physical Traits: These traits determine the laws of physics and nature on the plane, including how gravity and time function.
Elemental and Energy Traits: These traits determine the dominance of particular elemental or energy forces.
Alignment Traits: Just as characters may be lawful neutral or chaotic good, many planes are tied to a particular moral or ethical outlook.
Magic Traits: Magic works differently from plane to plane, and magic traits set the boundaries for what it can and can’t do.
