Magic Based on
Real Medieval Sources

Suitable for a medieval historical or fantasy RPG setting, Codex Superno takes you to a place where someone was just as likely to rely on a magic talisman for protection as they were upon steel armor and the edge of a sharp sword.
 
The world of Copernicus, Albrecht Dürer, and Christine de Pisan was awakening to reason and the liberating promise of technology, but it was also a realm of sorcery and the occult.
 

Prepare if you will to enter the capricious, mystical, syncretic realm of a character you might never have encountered before: the Renaissance Magus.
