Stern & Mond (Star & Moon) are two guns that serve a symbolic function within the Howling Voice Guild. These guns were made specifically for dueling, and Stern symbolizes "justice," and Moon symbolizes "betrayal," which are the two functions of the Howling Voice Guild. These guns were used in Elza and Kelly's duel, but the Elders made sure Mond was not loaded. Kelly knew this and was told to choose Stern. However, he intentionally chose Mond, resulting in his death. Elza took both guns after that and fled the guild. Since then, these two guns have been with Elza for years until they was used in the final duel between Clive and Elza, where Elza chose Mond this time.
