Spelljammer

When your journey across the world has grown tired and stiff, your adventures do not need to end. There is an entire cosmos of reality to explore. Alien landscapes, gigantic space beasts, and the titular Spelljammers that links all worlds. Pathjammer seeks to allow adventurers a means of escape terrestrial bounds and sail the stars using magically powered ships called Spelljammers.

Spelljammer® was originally created as an expansion by TSR for the world's most famous role playing game. It introduced a comprehensive system of fantasy astrophysics and provided players a way to link all of the various campaign settings active at that time. Since that day there have been small groups of players continuing to play Spelljammer® but officially it’s been unsupported since TSR was purchased by Wizards of the Coast. Towards the end of Dragon® magazines life there was a special module included at the end of one issue of the magazine. This homebrew module was a small love letter to Spelljammer®, a 3.0 update to some of the basic rules of Spelljammer®.
