Star Fragment

Star Fragments are star-shaped crystals appearing in Kingdom Hearts Birth by Sleep. They will have some significance to the storyline, Tetsuya Nomura stating in an interview that they were how King Mickey traveled the worlds. He also stated that they are known as Star Fragments in Kingdom Hearts Birth by Sleep, while the name is changed with the start of the first Kingdom Hearts to "Gummi Blocks." While the exact role these unique fragments will play remains unknown, it is shown through trailers for Birth by Sleep that Ventus is to discover King Mickey's Star Fragment in Neverland, another, and possibly the same, piece grabbed by the evil Captain Hook.
