Card Lores:Crystalwing Dragon

It is a fairy dragon born from "Crystal Tree", the tree of crystals which absorbs neither water nor light, but mana. The four wings on its back are beautifully transparent, comparable to crystals of high purity. By releasing its mana of high transparency, it can purify polluted water and soil. It is too cautious to show up in the public, and only few have witnessed it.
