From the back cover:
In factories throughout the city of Flint, months of ceasless toil by mages, engineers, and shipbuilders have finally concluded. Now well-wishers from across the nation of Risur have come to witness the launch of the world's mightiest vessel of war: the R.N.S. Coaltongue, impervious to spell and cannon and armed with fire that could slay even a dragon. On the docks, constables keep a close eye on celebrants and troublemakers; in the shadows, conspiracy and betrayal threaten this technological titan on its maiden voyage.
Meanwhile, on an island in the lush Yerasol Achipelago, Risur's traditional enemies unearth ancient ruins while crafting a metal masterpiece of their own. Cloaked in layers of secrecy, their designs creep toward completion, unknown to the outside world. But when a band of rookie constables thwarts the sabotage of the Coaltongue, the traitors responsible flee to that same hidden island, threatening to reveal the dangers that lie at the axis of the world.
The first adventure in the Zeitgeist adventure path takes the heroes from the metropolitan city of Flint to legendary Axis Island on the hunt for a traitor.
A fantasy adventure for venturesome heroes of level 1.
