A cinematic film still of a forgotten elven sky forest, shrouded in an ethereal light cast by glowing orbs of mana. Lush, ancient trees, untouched for ages, reach towards the heavens. Carvings of forgotten lore - glyphs and runes - adorn the celestial rock formations. Birds, butterflies, and fantastical creatures flit amongst sparkling mana droplets clinging to the deserted forest floor. A dramatic beam of sunlight pierces the scene, illuminating the remnants of a once-vibrant ecosystem. Utilize shallow depth of field and a vignette effect to draw focus on the foreground. Render the scene in high detail with a cinemascope aspect ratio, capturing the epic grandeur and dreamlike quality with bokeh. The overall mood should be one of haunting beauty and forgotten majesty, with a touch of film grain for cinematic realism.
