There are two tales in this one-shot. The first tale is written by Dan Breton with art by Chris Bolson. Red Sonja is in Khitai trying to stay dry during a fierce storm. She encounters a monk that guides her to an inn, a gamblers den that requires cleansing, thus the "Deluge" title.
This is a low key story in which Red Sonja plays the hand of the gods in helping to bring divine vengeance for being insulted by the greed and murderous intent of the inn-keeper and his companions.
