Obsidian caves underground

Generated from: Top-down hand-drawn 2D view of an underground cave zone, roughly 20 by 20 tile area, jagged black obsidian rock walls forming irregular chamber shapes with two narrow tunnel entrances, veins of glowing purple and cyan crystal embedded in the walls casting bioluminescent ambient light, scattered dark ore deposits on the cave floor, bone fragments and ancient torch sconces on the walls, deep black and rich violet palette with bright teal crystal glow accents, dangerous and dramatic atmosphere Drawn in this game's art direction: Hand-drawn 2D flat illustration, top-down orthographic view, clean ink outlines with visible natural brush texture, cel-shaded fills with subtle watercolour wash, warm but slightly muted fantasy palette of earthy greens amber stone grey and deep blue-violet, soft ambient lighting with clear directional shadows, chunky readable shapes that read clearly at small scale, no gradients except gentle atmospheric vignettes at zone edges Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one: take a named game's look and mood, never its characters, names or logos. No text, UI, HUD, logos or editor screens inside any image.
