For centuries¸ the intelligent races of Krynn have looked upward¸ toward the moons¸ planets¸ stars¸ and the very crystal sphere of Krynnspace. They have looked up and wondered¸ and gone back to their planetbound lives.
Meanwhile¸ on other worlds in other spheres¸ spelljamming ships have begun to venture into the Void; they have encountered vast evil - and vast wealth - in the trackless reaches of wildspace. Their ships have explored their own spheres and are even now moving toward Krynnspace.
And on Krynn¸ the art of spelljamming is stirring. Unbeknowst to most of the inhabitants¸ spelljamming ports are opening. Spelljammers from other spheres are exploring the planet¸ and explorers from Krynn are rising into the sky and into space. Soon the mysteries of Reorx¸ Chislev¸ the Black Clouds¸ and the dark planet Nehzmyth will be yielded up - or will destroy those seeking to investigate.
