"High Adventure in the Steam Age"
Adaptation of the R. Talsorian RPG to GURPS
From the back cover:
Imagine a world very much like 19th-century Earth, but with wizards and swashbuckling heroes . . . and Dragons and Faerie! A world where Kabbalistic magick meets steam-powered technology against the backdrop of imperial intrigue, and where the writings of Doyle, Shelley, Verne, and their contemporaries are fact. This is the world of Castle Falkenstein.
