(Visual: Start with a wide shot of the luminous lion in its cosmic landscape. Subtle animation of glowing elements and sky.) ​(Narration: Calm, mystical voice, slightly echoing) ​"Beyond the known constellations, where cosmic dust drifts in eternal slumber... glides the Nebula Serpent." ​(Visual: Slow, gentle zoom towards the lion, focusing on its luminous details. Imagine the lion is observing this unseen creature.) ​"It coils through the vastness, its scales mirroring distant galaxies, its eyes holding the light of newborn stars. A living river of starlight, it charts the ancient paths between worlds." ​(Visual: Hold on the lion, with cosmic background gently moving. Subtle magical twinkling sounds, maybe a low, drawn-out hum or whisper.) ​"Though unseen by waking eyes, its ethereal presence weaves the cosmos, a timeless echo in the silent, swirling deep." ​(Visual: Fade to black or title screen with text like "The Nebula Serpent" or "Cosmic Drifter.")
