Glyph-Glow Obelisk in the Silent Cave

A towering ancient obelisk rises from a dark cave floor, rendered in high-detail concept art. The obelisk is carved from obsidian-like stone, etched with glyphs that glow faintly blue-green. Damp cave walls with stalactites and moss; water drips form ripples in a still pool around the base. A narrow beam of light from a crack high above slices through the gloom, illuminating the obelisk and casting dramatic shadows on rough rock. Mist swirls in the air, highlighting the runic inscriptions and weathered texture. The scene melds fantasy and exploration vibes with painterly textures, cinematic lighting, and a color palette of deep blues, teals, grays, and warm amber glows from the glyphs. Concept art mood: mysterious, ancient power, silent awe.
