Spelljammer

Spelljammer is a popular setting for Dungeons and Dragons, first appearing in the Advanced Dungeons and Dragons edition of the game, which brings the players into space. While it takes place among a vast universe, Spelljammer maintains the fantasy of DnD. It uses unusually shaped ships, powered by magical helms, to travel between the stars. And the ever changing will of the gods and the arcane holds just as much sway as on a single world.
