Design an icy, frozen cavern with bioluminescent creatures and glowing ice formations for "G/play" in the style of the game's splash art from world building. The artwork should feature dramatic lighting effects, creating deep shadows that enhance the mystical atmosphere within the cave. A glow emanates from the crystals, illuminating intricate details on their surface, adding to the overall ambiance of otherworldly beauty. --ar 35:18 --niji 5
