Inner Planes

The Inner Planes are the four Elemental Planes and three Material/Energy planes that, along with the Transitive Planes, and the Outer Planes, make up the Known Universe. The Elemental Planes are home to some deities, and many elemental beings, while the Positive and Negative Material/Energy Planes are stocked with the remains of the faithless dead from the Prime Material/Energy Plane.

Positive Material/Energy Plane
This is the plane of creation and life, and is the total opposite of the Negative Energy plane. Despite the plane's life giving effects, living creatures entering the positive energy plane quickly become overloaded with life energy and may explode. Necromantic spells harming undead and "turn undead" abilities draw on this plane and most deathless creatures have an inherent connection to it.

Negative Material/Energy Plane
This plane is the home of stagnation, entropy, and undeath. Any unprotected living creature exposed to the Negative Energy plane has its life force rapidly drained and will die when they run out. Many necromantic spells, including bolstering undead and "rebuke undead" abilities, draw on this plane and most undead creatures have an inherent connection to it.

Prime Material/Energy Plane
The Prime Material/Energy Plane consists of worlds that balance between the spiritual forces of the Outer Planes and the physical forces of the Inner Planes. The Prime Material Plane is where the more 'normal' worlds exist, many of which resemble Uthe.
