Gothic-inspired aquarium, ornate Victorian-style frame, mysterious dark blue water, eerie glowing jellyfish, schools of small bioluminescent fish, delicate seaweed swaying gently, old Gothic-style stone castle ruins in the background, misty fog rolling over the castle walls, dimly lit by flickering candles, intricate carvings on the tank's wooden lid, worn leather-bound book lying nearby, mysterious ancient artifacts scattered around, warm golden lighting, cinematic composition.
