Deep in the bowels of an abandoned mine, the Defenders uncover a secret destined to shake the entire realm of Rados to its foundations: The existence of a Ninth Sigil. And it doesn't take long before the evil Lord Nazmul sends his agents Malco and Flinch to claim it for the Order of Infinis. Worse than that, Kara's boots start to act up and wishes she was not so helpless and that the Di-Gata Defenders would stop treating her like a baby.
