What is Spelljammer?

	Spelljammer is a campaign setting for the Advanced Dungeons and Dragons role-playing 
game first published by TSR, Inc. in 1989.
	The Spelljammer setting is unlike any other AD&D campaign setting, because the idea of 
fantasy-based space travel is its basis.  It allows characters to travel not only through space 
but to other campaign worlds as well using vessels such as a galleon sailing ship, certain 
fantasy creatures or other types of ships not normally found on the surface of a planet.  
	The Spelljammer universe treats the fantasy realms of the AD&D game as the "real" 
universe.  Magical kingdoms and fantastic creatures do exist and do not interfere, but rather 
coexist with space travel.
