고대 지도에서 솟아오르는 발광 심해 괴수

A majestic, bioluminescent leviathan rises from a swirling, uncharted ocean depicted on an ancient, rolled-up parchment map. The map itself appears to be a portal, with ethereal light bleeding from its edges. Crudely drawn coastlines and fantastical islands surround the creature. The style combines the aesthetic of aged cartography with the visual flair of cosmic horror, rendered in a dark, painterly manner with glowing, unnatural highlights.
