Paul Westermeyer's Map of the Flow

Philogiston Navigation

The Complete Spacefarer's Handbook quite properly lists Navigation, Philogiston seperately from Wildspace navigation, but does not explain why. The reason is fairly simple, there are precious few landmarks or navigation aids in the flow. So how does one get from place to place? The easiest method is to follow a flow river, and that is done by determining the predominate colors of the areas flow. There are many major flow rivers through the philogiston, and each has a distinctive color scheme that makes it distinct from the others. Since most crystal spheres remain in relatively stable positions within the flow one can navigate by counting the spheres passed as one follows the river. River intersections provide another means for determing location, as the colors do not intermix (Sages still debate the reasons for this). Traval to sphere's outside a major flow is much more time consuming and difficult: the navigator must first determine his/her exact position within the sphere to be departed, then he/she must determine at what angle from the sphere the destination sphere lies and plot a direct course to it. Obviously this method is very risky, though some navigators are so good they hit everytime. The navigation proficiency roll should be given a -6 penalty when attempting Philogiston navigation without a river.

Spheres

Refuge

Arcane controlled sphere designed by Ed Greenwood and found in Dragon #159.

Winterspace

From the Cloakmaster novel The Radient Dragon, contains the planets Radole and Armistice.

Lankhspace

Home of Fritz Lieber's Lanhkmar.

Redeye

Mentioned in SJR1 Lost Ships. A mostly deserted, dangereous sphere.

Moragspace

Detailed in SJS1 Goblin's Return. Home of Gammaro base.

Taurusspace

My creation. Home of the Tauran Empire (Minataur's ruling over humans).

Greatspace

Rare "single government" sphere, from SJA3 Cyrstal Spheres.

Faeriespace

Strange sphere, from SJA3 Crystal Spheres.

Darkspace

Undead controled sphere with no fire body. From SJA 3 Crystal Spheres.

Sea of Shadows

A magic dead sargasso in the philogiston. from SJR1 Lost Ships.

Gromspace

Sphere I thought up which is noted for holding the Gromman homeworld.

Ilsigspace

The world of the Thieves' World anthologies is in this sphere. I think the Nisibis, at least, are Spelljammer aware.

Vodoni Empire

From SJA4 Under the Dark Fist. In my game they mostly send raiders throughout the spheres.

Terraspace

This sphere uses the Earth at the center of the system organization and represents our solar system as it was believed to be during the Darkages. However, magic works. Some individuals are aware of spelljamming. Use the Age of Charlemange and Vikings Historical accessories to get the feel of this sphere.

Solspace (The Space: 1889 crystal sphere)

Located away from any major rivers this was only recently discovered by an Elven Man-o-War. Only artifact level magic (like Helms) and spells upto 2nd level function here. I'll post more on this later.

Falxspace

Sphere of Falx, mentioned as a Mindflayer planet. I use the "Sunset World" Dragon #150 to get the right feel for this place.

Darnannon

An Elven sphere mentioned in Dungeon #36.

Pirtel

Mentioned in Dungeon #36 and #45. A fairly standard sphere.

Talangran

The sphere holds the Talangran Empire, a spelljamming aware groundling nation with superior technology and a thirst for Elven slaves. In my campaign the Talangran Empire has begun to expand into the stars. Inspired by "The Lady Rose" Dungeon #34.

Korvspace

Elven dominated sphere from Polyhedron #81.

Herdspace

Very strange crystal sphere from The Maelstrom's Eye.

Heartspace

Home of Crescent, planet holding the Great Archive from The Broken Sphere.

I haven't placed Mystaraspace, Bloodspace (Birthright), or Dragonspace (Council of Wyrms) because I want them to be a surprise for my players. I'm thinking of having the Heldannic Knights explode into space in a big way. :)
