From publisher blurb:
Based on Faith Hunter’s apocalyptic fantasy trilogy (Bloodring, Seraphs, and Host), and containing new fiction — several vignettes and a complete short story about Thorn St. Croix, the Rogue Mage roleplaying game takes you deeper into the world of Thorn, and also lets you play neomages, kylen, humans, and mules in the battle against the Darkness.
Additionally, the game reveals how magic works in the Faithverse, and details how other parts of the world are faring after the apocalypse.
Rogue Mage uses only a 20 sided dice (d20) to play. The game system uses the world’s most popular roleplaying game rules set for superhero games, modified for ease of play. Character creation is through point buy, and the system contains no classes.
