Alternate multiverse

If anyone has any comments, criticisms, or suggestions; I'dlike to hear
them :)

    The multiverse can be pictured as a sphere that is ordered around six
poles while floating in a sea of chaos. While this  is a popular model and
severs as well as a flat map does on a sphere, it is only a model. There
are numerous exceptions to the general order of the sphere; much like the
presence of  "space-time anomalies" that abound in Star Trek. An individual
plane can be desribed by its "distance" from each of the poles.
    There are three different axis for the sphere: Heaven/Hell,
Aether/Mechanus,and  Astral/Dreamworlds. Each axis has two extremes that
are opposed to each other. Each extreme is a source of one of the basic
forces in the multiverse and that force is strongest there and get weaker
the farther you get from the source. 
    The three primary resources that inspired this vision of the multiverse
are the AD&D Planescape (tm) and Spelljammer (tm) settings and the
excellent Primal Order (tm) series of books by WOTC. 

   Heaven: these are the planes closest to the Font which is the ultimate
source for angelic primal. Good-aligned effects are greatly strengthened
and diabolical effects are weak. 

   Hell: these are the planes closest to the Wick of The Flame;the source
of diabolical primal. The spirits that are supported by the primal energy
from the Throne of Hell are known as devils; as opposed to the evil spirits
that are not so supported and are known as demons. A good metaphor for the
relationship between the two is to visualize a vast pit [Hell] surrounded
by plains that are in turn surrounded by mountains and valleys [Abyss]. The
Wick is in the pit and is ruled by devils; while the demons live 
outside the pit. Some try and invade and take the Throne of Hell and others
merely profit from this. Other factions ignore this struggle all together. 

   Aether: these are the planes of energy (also known as the Elemental
planes) and permeate the sphere as the Aetheral border. These are the
planes where magic is the most powerful and science is the weakest. The
Couts of Chaos [Amber novels] are a good example of an Aetheryal plane. The
Courts of the Faerie are also located here and reflect the magical nature
of these realms. Many planes use the Aetheral border as an relatively easy
means of travel [this replaces the phlogistron found in 
Spelljammer (tn); there are no crystal spheres but there are some
structures found in the flow]. The border is mostly Wild Mana and most of
the jamming ships that travel through it are surrounded by some sort of
field that reduces the mana level to high or normal. There are numerous
currents and eddies in the aether that complicate travel. There are many
different types of engines for travel in the Flow; ranging from magical
"helms" to scientific hyperdrives.

   Astral: these are the planes of mind and permeate the planes as the
astral border. These planes are where psionics is the most powerful and
spirits are the weakest. The Illithids are thought to have originated near
these planes. The Astral border has both shallow and deep aspects. The
shallow aspects of the astral are closest to the planes that it touches and
reflects the structures found on these planes. The deep astral is nearly
formless.

   Dreamworlds: these are the planes of spirit and extend across the sphere
as the spirit realm.This is the area where spirits are the most powerful
and psionics is the weakest. Many Lands of the Dead (tm) are located near
this pole. 

   Mechanus represents the planes of matter and provide the physical
structures in the multiverse. Science is the strongest here and magic is at
its weakest. Amber is a good exampleof a mechanus-type plane. Much of the
technologies from these realms do not work in other planes; generally, the
more complicated the device the more plane-specific it is .
 
In the center of the sphere, the planes are tightly packed and the barriers
between them are thin. At (or near) the center is a city that has shifting
portals and gates to much of the rest of the multiverse. It is founded on
interdimensional trade. Sigil is a good inspiration; though Cynosure [from
the Grimjack comics] is a better one.
