Celestial Ruins: Ancient Temple Under Starry Skies

For the cover, imagine a vast, celestial sky filled with swirling stars and glowing constellations, casting a divine light over an ancient, ruined temple perched on the edge of a cliff. At the center, the Heartstone glows with an intense, golden light, suspended above the altar as if it’s calling out to the universe. The silhouette of a young woman, Mara, stands before the stone, her figure outlined in light, her expression fierce yet determined, holding a sword in one hand and the Heartstone in the other. The background fades from deep purples to fiery oranges, symbolizing the clash of light and darkness, while ethereal energies swirl around her, representing the power she holds. The title "The Forgotten Chronicles" is emblazoned in bold, metallic lettering at the bottom, with elegant and intricate filigree surrounding it, giving it a regal and ancient feel, as though the cover itself holds a piece of forgotten history.
