From publisher blurb:
Welcome to part one of the critically acclaimed ZEITGEIST adventure path!
This is the 5th Edition version of this adventure.
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, enemy spies put their plans into motion, clouded with secrecy...
An adventure for heroes starting at 3rd level.
