The Elemental Stones (also refereed to as Sacred Stones or Magic Stones) are four objects that embody the primordial elements of the cosmos; with each stone possessing a unique power based off of the element they possess.
Due to the power of these items, each was placed deep within a labyrinth (Dribble Fountain, Cackle Mound, Golem Mine and Twinkle Palace). In ancient times, the stones were protected by Guardian Genies. However, now they are protected only by the bosses that have taken up residence in the labyrinth.
During the events of Shantae, Risky Boots travelled around Sequin Land in search of these stones, so that she could power the Steam Engine indefinitely. She allowed Shantae to recover all the stones so that she could steal them from her. At the end of the game, Shanae learns that Risky has used the stones to power her All-Purpose Steam-Powered Tinkerbot. Shantae destroys the four stones, negating their power and allowing her to destroy the Tinkerbot's Steam Engine.
