Underworld is a collaborative storytelling experience for 3-6 players. It can be played over the course of a few short , 1 hour sessions or as a longer one time experience of 3-4 hours. In Underworld, players take turn controlling a wanderer called the Exile as it confronts the dangers and enigmas found in the Underworld on its way to the Underworld's center. The Underworld is dangerous, and it is not gauranteed that the Exile will reach the Heart! Each play of the Exile's Descent is meant to be a different and challenging excercise in improv and storytelling.
