A plane is a dimension of existence. There are a range of planes, some
of which are detailed below.
The Material Plane:
The "main" plane, the Material Plane is the home of most creatures. The
various PC races are from the Material Plane and most of them spend
their entire life there.
There are no special game effects for being on the Material Plane; the
Material Plane is the default assumed by the rules. When in doubt,
assume the Material Plane follows the same physical laws as the real
The Astral Plane:
The Astral Plane is the plane closest to the Material Plane. Spells
cast to leave the material plane usually take the caster to the Astral
Plane and vice versa. No creatures are native to the Astral Plane.
the Astral Plane, there are points known as "planar windows". A planar
window is tied to one particular plane and you can use magic to shift
to that plane via the window.
While on the Astral Plane, gravity
is subjective. You can, as a free action, change the direction gravity
pulls you (no gravity is the default and can be chosen).
four Elemental Planes are the source of the fundamental parts of the
universe. Air, Earth, Fire and Water; each provides one part of

planes are infinitely large. However, whenever someone enters an
elemental plane, they always appear in the same area.
Plane of Air:
far the safest of the Elemental Planes, the Plane of Air is an endless
void of air. The plane of air is the only elemental plane with
breathable air on it naturally.
Plane of Earth:
The Plane of Earth is an endless maze of caves and caverns. To make navigation worse, the cave walls are slowly shifting around.
Plane of Fire:
Plane of Fire consists almost entirely of endless fire. Creatures on
this plane take 3d6 fire damage every round, unless the creature is in
one of the plane's scattered safe areas. These safe areas are much
Plane of Water:
Plane of Water is filled with water. However, the plane has no water
pressure, making it easy enough to create an empty area.
The three Alignment Planes rule over the spirit. Each tied to part of the alignment spectrum; Good, Neutral and Evil.
a creature dies, its soul is sent to the Alignment Plane matching its
alignment (souls in a plane are known as "patrons"). All alignment
planes are infinitely large. Patrons do not need to eat, sleep, drink
or breathe, but can do all these things if they wish.
can not die; any effect that would kill them instead destroys them for
1d6 hours, after which they reform at their point of death. Patrons can
not leave their alignment plane unless they are brought back from the
Special Note: Divine casters go to the alignment plane where their god/goddess lives, even if their alignment isn't the same.
Realm of Light (good):
Realm of Light is an infinitely large kingdom. A peaceful land, none
need want here. Anything you could desire, at your fingertips. The lack
of challenge can bore some, however.
Realm of Shadow (neutral):
The Realm of Shadow is an infinitely large castle. Large areas to see and explore.
Realm of Darkness (evil):
Realm of Darkness is an infinitely large series of caves. At first
glance, it looks like the plane of earth. Not a bad place; the company
might be problematic, though.
