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.
