From publisher blurb:
Frog temples, ray guns, and more.
Products of alchemical evolution, members of the Frog Clans and their allies represent two new playable races of humanoid amphibians. Hailing from a mysterious land beyond the stars, these races now preside over ancient frog temples in the hearts of swamps everywhere. Led by templars equipped with technological relics and altered through strange alchemical and surgical experiments, these new races showcase dozens of new character options.
Spur your continuing evolution with new alchemist discoveries. Become a test subject for experimental body modification procedures. Wield circuit-threaded weapons, ray guns, and other strange gear. Worship at the altar of high technology with a new Technology cleric domain. All of these options and more are available to the boggards of the Frog Clans and to other characters who cross their path.
