Henghis Hapthorn

Henghis Hapthorn is the foremost penetrator of mysteries and uncoverer of secrets in a decadent, far-future Old Earth, one age before Jack Vance's Dying Earth. A superb rationalist, he has long disdained the notion that the universe has an alternative organizing principle: Magic. But now a new age is dawning, overturning the very foundations of Hapthorn's existence, and he must struggle to survive in a world where all the rules are changing.

It was bad enough when Henghis Hapthorn, Old Earth's foremost discriminator and die-hard empiricist, had to accept that the cosmos was shortly to rewrite its basic operating system, replacing rational cause-and-effect with detestable magic. Now he finds himself cast forward several centuries, stranded in a primitive world of contending wizards and hungry dragons, and without his magic-savvy alter ego.
