Wraith of the Deep: Underwater Cave

Panel-ready comic book illustration of a wraith in an underwater cave. Bold black ink outlines, heavy halftone shading, and high-contrast lighting. The translucent, ghostly figure wears a tattered cloak that flows with the underwater currents, a pale blue-white glow emanating from its core. The wraith hovers near a jagged rock shelf, wisps of energy curling around its hands as bubbles rise. The chamber features submerged stalactites and stalagmites, coral growths and bioluminescent algae casting eerie green and cyan light. Sunbeams pierce the water from an opening above, creating refracted caustics and a dreamy underwater haze. Include silhouettes of small fish, drifting debris, and sediment swirls to imply motion. Color palette: electric blues, teals, and icy whites with stark black shadows. The mood should be eerie, otherworldly, and adventurous, suitable for a dark fantasy comic panel.
