A supposed Dark Keyblade of the Realm of Light, possibly the only Keyblade of Darkness created in the Realm of Light and allowed to stay, while still weak in his powers it allowed Shadow to possess the original of this Keyblade and not some copy like the one created by the Keyblade of the World's Hearts (the Kingdom Key), this Keyblade allows Shadow to express much of his uncontroled Darkness and incomplete powers.
