When the leader of the ruthless Technic League calls in a favor, the mild-mannered alchemist Alaeron has no choice but to face a life he thought he’d left behind long ago. Accompanied by his only friend, a street-savvy thief named Skiver, Alaeron must head north into Numeria, a land where brilliant and evil arcanists rule over the local barbarian tribes with technology looted from a crashed spaceship. Can Alaeron and Skiver survive long enough to unlock the secrets of the stars? Or will the backstabbing scientists of the Technic League make Alaeron’s curiosity his undoing? From Hugo Award-winner Tim Pratt comes a fantastical adventure of science, savagery, and the vagaries of the human heart, set in the world of the Pathfinder Roleplaying Game and tied into the Iron Gods Adventure Path.
