Umbragia: Realms of Shadow is a d20 setting that tries to avoid the standard fantasy trappings, like elves. The core rulebook includes 19 races (a number are based on animals), and the magic system is inspired by S. John Ross's work, including the popular UMana system for GURPS (complete with rules for backfires). The PDF also includes an extensive history, map, a detailed description of the nations of the world, animals and monsters that are unique to the setting, and new magic items.
