Tarniss is an ancient world. There are islands of civilization, frontier settlements, and large tracts of untamed wilderness. The landscape is littered with impossible ruins built long ago by a lost race of titans with forgotten technologies from a previous golden age. Various civilizations have ruled the lands, rising to power then fading to history. Factions now vie for survival and dominance in this chaotic world. The skies are ruled by clans of sky lords and their flying citadels. The seas are ruled by strange fish-men. The earth is pockmarked with caverns, ruins, and dungeons that extend far below to eldritch cities and an inner primitive world. Beyond the skies the heavens are navigated by astral ships that travel on the aether to the moons and other worlds.
