If OctaNe satisfies fills post-apocalyptic hard rock niche, then HorsePower is for the fantasy hard rock niche. Designed to be used with the OctaNe system, HorsePower is an amalgamation of all things that are cool about fantasy, splashed with a dose of rock music. Vikings? Cool. Troll-slaying dwarves? Cool. Dionysian parties? Cool. Dying young from a minor infection? Not cool.
HorsePower is designed with the same fundamental ideas as OctaNe. Except instead of cars, there are horses. And all the guitars are acoustic, but that doesn't stop killer riffs from being played...somehow.
