Mount Targon

Like any place of myth, Mount Targon is a beacon to dreamers, madmen and questors of adventure. Those who survive the arduous journey to the foot of the titanic mountain find a sky shimmering with celestial bodies; the sun and moons, but also constellations, planets, fiery comets that streak the darkness, and auspicious arrangements of stars. The people living at the mountain’s base believe these to be aspects of long-vanished stellar beings, creatures powerful and ancient on a scale beyond human comprehension.
