Stone Tablet

The Stone Tablet (Japanese: ストーンタブレット, Sutōn Taburetto) was a tablet that originally resided in the Benham Museum. It first appeared in "Tenkai Dragon Cube". When Guren and Ceylan came close to it, the writing on the tablet glowed and it transformed into the White Key. The stone tablet was found on Quarton on the wall inside of a cave.
