My homebrew is a swords & sorcery, rare magic world set in a late dark ages/early medieval world that is just beginning to relight the flame of civilization and learning. Barbarian hordes and worse things ravaged the lands a few hundred years ago, and the former dominant empire is just beginning to get back on its feet. Numerous small kingdoms and duchies exist that war on each other for resources, land, and power. The only PC race is human, as dwarves, elves, etc are mythical creatures believed by most people to be legend. Orcs and goblinoids are fairly common, but they worship dark powers that seem bent on the destruction of civilization. There are numerous horror undertones to the world, with strong Lovecraftian (eldritch horrors) and Faustian (infernal) undertones, as well as some elements of gothic horror. Because of the chaotic nature of the world, the PCs can have a big impact on the outcome of events, for better or worse.
