A massive rift opens in the icy skies above Glaciara, splitting the heavens with swirling black energy. Below, the crystalline terrain glimmers faintly, contrasting with the encroaching darkness. Shadowy tendrils pour from the rift, reaching toward the frozen plains as an army of amorphous shadow-bound soldiers begins to descend. The towering Crylodian structures of radiant ice stand in defiance, their luminous glow slowly dimming under the oppressive void. The scene captures the clash of light and shadow, with a frozen battlefield marked by the desperate resistance of crystalline warriors against an overwhelming, otherworldly force."
