Pass through any of the black holes that dot the universe and you enter Slipstream, a pocket universe of shattered worlds. Slipstream is home to myriad aliens, but it is also their prison, for there is no escape.

Amid the fragments of worlds rules the science and flavor of 1930s Saturday morning pulp serials, for Slipstream is a realm of square-jawed heroes, ray guns, weird science, and rocketships. It is a realm where the morals are black and white, where good triumphs over evil, and where danger lurks at every turn.

Ruling over Slipstream is the diabolical queen Anathraxa and her horde of Hand Maidens, Primals, and Minions. All bow before her, paying tribute to avoid destruction. None have had the courage to stand against her forces, at least not until now. For this is the role your heroes will take: bastions of light against a dark foe! Strap on your rocket pack, charge your ray gun, and prepare to blast off on wild and exotic adventures!
