Sting is a White Dragon Slayer and a Mage of the currently strongest Guild in Fiore, the Sabertooth. He was raised by the Dragon Weisslogia, who taught him White Dragon Slayer Magic. He eventually used this Magic to kill Weisslogia, in order to become a "real" Dragon Slayer. At some point in his life, Sting also implanted Dragon Lacrima into his body, thereby making him a third-generation Dragon Slayer.
