Joe is a good sleeper, very good - some would say the greatest in Chasmton. But there are just some things you can't sleep through; good lovin' and bad rockfall. Joe doesn't get much lovin these days, but rockfall has cut off his town's water supply from the dam at the top of the chasm, and you (lucky devil) have the chance to go along for the long and perilous ride.
