Mystaraspace is the crossover campaign setting where Mystara meets Spelljammer. There have been several attempts to combine the best of the two campaign settings, but so far nobody seems to have pulled everything together. (Some of the people attempting to do this have not even got as far as naming the planets, so planets are often referred to as "M-Mars" or "M-Venus".)

At the moment, there is a group of people over at The Piazza, who are attempting to springboard off of the earlier attempts and name all of the planets in Mystara's system.

• Mystaraspace (started by multizar)
• Planets of Mystaraspace (started by cab)
• Planets of Mystaraspace - Valerias, the second planet (started by cab)
• [Mystaraspace] Adjacent Solar Systems/Crystal Spheres (started by Havard)

Watch this space, as more threads will be added here as they are created.

Note: Any planets or moons with a "M-" prefix are placeholders and will need to be renamed later.
