Doran the Dragonlover studied and described Lapis Adders in Secrets of Deltora. He also mentioned how the snakes featured in the numerous superstitions of the Mere; seeing a Lapis Adder is considered lucky, and Lapis Adder skins are even luckier. Their skins are very valuable and are often worn from peoples' belts, having been passed down as family heirlooms.
