Report on the Phlogiston
Based on information from the Phlogiston Flow Map supplied by Capt Yehonahan Ahab of the Spelljammer Pequod and translated by Mr Dworkin, Investigator to Her Glory Empress Star.
Arcane Space, a part of the Prime Material Plane, is divided into three zones or areas of space: Wildspace, the Phlogiston, and Void Space.
Wildspace is where all the planets are; each planetary system is contained within a Crystal Sphere, which is a physical object twice as large in circumference as the distance from the sun to the furthest orbital body. This space inside the crystal sphere is called Wildspace. Wildspace behaves much like what we know as space; it is a vacuum, and can be cold, but due to the crystal spheres, often it can be somewhat warm. Every crystal sphere is a little different.
Wildspace and Crystal Spheres are widely varied in characteristics; some are simple spheres, some have giants roaming the spheres, some have a nice hot sun at the center, some don't. In spheres where there is a sun, the temperature of space is usually warm and comfortable; however it can be dreadfully hot depending on a lot of factors. Planets orbit their sun, which is also called Primary, categorizing it with the planets as celestial bodies. These orbits are varied in distance and sometimes trajectory, much like the planetary systems we are used to. The stars one sees when one looks up into the night sky are NOT other suns, as the ancients used to believe, but rather magical crystals embedded in the inside surface of the crystal sphere. Some of them have obvious functions, such as operating the gates to get in or out of the crystal sphere. Others, who knows?
Surrounding all the Crystal Spheres is a thick gaseous matter called the Phlogiston.
The Phlogiston surrounds and connects all Crystal Spheres. Phlogiston cannot exist inside a Crystal Sphere, probably due to its flammable nature. Phlogiston can be ignited by as little as a lit candle, and the resultant conflagration can spread to many hundreds of miles around the center. Everyone knows, if you travel through the Phlogiston, you do NOT use anything with fire, unless you have it contained. The Phlogiston has a planar attitude, as it is several times as thick at its "Center" as it is above. The Crystal Spheres are described as "bobbing" in the Phlogiston, and in fact it is often referred to as a "sea". Plogiston that exists above this plane of density, the "atmosphere" of space, if you will, is the same material as that below, but much thinner. The "atmospheric Phlogiston" reacts to the "flow rivers" with a similar movement, creating "air currents" which can be utilized by sails and rigging to steer and drive spelljamming ships. The "planar" nature of the Phlogiston suggests a gravitic source somewhere below it, but nobody has been able to document such a source.
If you wish to travel from one Crystal sphere to another, say from Oerth to Toril, you will enter and navigate in the Phlogiston. The Phlogiston forms many flows, sometimes called rivers, that accelerate the movement of any ship inside it by a factor no one has been able to determine; speed is impossible to determine as there are no markers to use as a guide; one simply knows roughly how many days it will take to get from one sphere to another. Travel outside of the flows is possible, but much slower; travel inside Wildspace normally reaches about 4,000,000 miles a day, as an average. This speed varies according to the engine design of the particular spelljammer ship. In the Phlogiston outside of the flows, speed slows to just about double this speed, a fraction of the speed inside a flow. Also, the non flow areas tend to be inhabited by space born creatures, or hide outs for criminals. It's dangerous and slow, but if you don't want to be followed or detected in the Phlogiston, going outside the flows is a good idea.
The Phlogiston was assumed to be the end of it when men and demi humans started to explore. It extends far "above" and "below" the spheres, so the assumption was that the Phlogiston was the universe, holding all the crystal spheres inside it. What they found out however, after enough exploration, was that there was an even bigger area of space, they called Void Space. They now understand their universe is a completely dark, starless, frigid void. There is no idea if the Void has limits, or where the Phlogiston is in relation to the "limits" of the Void; perhaps they never will.
The only recorded properties of Void Space is that it is entirely dark, appears to be entirely empty, and is as frigid cold as one will ever experience. Travel in Void Space is extremely dangerous, as the cold will eventually affect the oxygen inside your ship, and you will freeze to death. There is nothing in the Void, as far as anyone knows, so there's nowhere to gain supplies of any kind. Navigating in the Void is obviously dangerous and essentially impossible. For a while, if you look down you will see the pinkish glow of the Phlogiston, but eventually even that light gets lost, and you have no compass point to guide you at all. It is surmised that there have been many a ship go lost in the Void, but no one has recorded a successful discovery mission thus far.
