The Dark Dragonstone is a dragonstone that allows a Manakete to transform into a Dark Dragon. It only appeared in Fire Emblem: Mystery of the Emblem, but was an unused item. In Mystery of the Emblem, Tiki is capable of using the Dark Dragonstone via hacking or cheating (similar to the Earthstone), however, unlike the Earthstone, the game will be glitched graphically. Also like the Earthstone, the Dark Dragonstone does not follow the story at all and is unobtainable by normal means.
