Hordes is a miniatures tabletop wargame set in Privateer Press's Iron Kingdoms universe. It's probably best described as a Fantasy world with steam driven technology. Thus magic, technology, elves, and dwarves all present in the game. Hordes, however, focuses on four factions from wilderness of Iron Kingdoms: Trollbloods, Circle Orboros, Skorne and Legion of Everblight.
