Rubiss is a creator Goddess who appears as the principal deity in several Dragon Quest games.

Rubiss isn't mentioned in early versions of Dragon Quest, but she is mentioned briefly in the smartphones remakes by the Sage in the Sanctum, who bestows the Hero with the Rainbow Drop, as well as the Sage in Cantlin, who tells the Hero about the location of the Mark of Erdrick. The two sages have the exact same dialogue, as many of the citizens of Alefgard share dialogue with other characters of the same NPC class in the aftermath of the Hero's victory over the Dragonlord. However, she is set to appear in the HD-2D Remake with an expanded role and Princess Gwaelin of Tantegel is said to communicate with her. In addition, the Faeries' leader, Dream-Whisperer, is attempting to summon her after she left Alefgard following Zoma's defeat.
