You are the Captains of the Crossed Swords, and your might, mutations, and wits have conquered all the lands you know. But you’ve long suspected that there are many other lands layered above and below, and heretics say that your world is truly a vast ship traveling from one sphere to another. What new conquests await? Play TSR’s original science fantasy RPG with a GM who’s been described as “welcoming and personable... droll and diabolical”.
