The following text charts the changes that have been made to the
Material Plane for the purposes of the Iourn Cosmology. Players
should assume that any published rules for the material plane that
do not directly contradict to following should stand. Details of
the Material Plane can be found in Dungeon Master's Guide
p147, Manual of the Planes p41 and The Planar Handbook
p135.
Material Plane Traits
- Normal Gravity
- Normal Time
- Finite Size (the world of Iourn)
- Alterable Morphic
- No Elemental Traits (although the waxing and waning of
the moons can create periods when certain elemental or energy
types are dominant)
- Mildly neutral-aligned
- Normal Magic
Planar Connections
The following planes are directly connected to the material plane.
In order to reach planes that are not on this list a character must
traverse a transitive plane, usually through the use of some form
of magical spell or device. The rings that surround Iourn can open
portals to any world including the elemental planes. However, these
are not direct links and make use of the Astral Plane in a similar
manner to a teleport spell.
Transitive Planes
- Astral Plane: The material plane is coterminus with the
Astral Plane. Doorways between the Astral and the Material world
exist where adventurers can physically enter Astral space. Because
of the closeness of the Astral Plane certain spells can reach
out to the Astral from anywhere on the material plane and create
a connection. Spells such as dimension door and teleport
function in this manner.
- Ethereal Plane: The material plane is both coterminous
and coexistant with the Ethereal Plane. Ethereal creatures can
exist simultaneously in the ethereal plane and in the material
world. It is very easy to cross over to the Ethereal at certain
points or using relatively low-level spells.
- Shadow Plane: The material plane is both coterminous
and coexistant with the Plane of Shadow. Shadow creatures can
exist simultaneously in the plane of shadow and in the material
world. It is very easy to cross over to the Shadow at certain
points or using relatively low-level spells. Certain illusions
draw upon the plane of Shadow to create semi-real effects.
- Region of Dreams: The material plane is coterminous with
the Region of Dreams. Dream forges a special connection with every
thinking creature. When such creatures sleep they create a Portal
of Sleep in their minds which allows the trained Dreamer to step
into the Region of Dreams. Dream can also be accessed by certain
spells. Some locations in the Material World are particularly
close to Dream (such as the Cave of Fear in the Karundite mountains
of south-westerly Norandor). In such places, sleepers are sucked
into the Region of Dreams whether they are skilled Dreamers or
not.
Outer Planes
- The Great Dark: The material plane is coterminous with
the Great Dark in seven locations. The Great Dark is located on
what is effectively the southern pole of Iourn. It is surrounded
by the Enceinte and can be entered via one of the Seven Gates
of Perdition. There are no known portals into the Great Dark elsewhere
on the Material Plane.
- The Greymere: The materal plane is coexistant with the
Greymere, however direct access to the Greymere from the Material
world is utterly impossible without special rituals, artefacts
and incantations.
- The Heavenly Realm: The material plane is conterminous
with the Heavenly Realm via a region known as the Weirlands. Quite
what trails an adventurer would need to suffer to reach such lands
is unknown. Well, it is known but I'm not telling.
- Void: The material plane is coterminous with the plane
of Void. Void completely surrounds the World of Iourn just beyond
the flailing rings of light and energy. A creature capable of
flight can simply travel from the Material World to Void by crossing
the boundary. There are no portals to Void on the surface of Iourn,
although it is obviously possible to access Void via the transitive
planes.
