A cobalt glass orb, cradled within the skeletal hand of a long-forgotten giant. Cracks spiderweb across its surface, each fissure pulsing with an inner light that shifts and swirls like captured nebulae. Ancient runes, etched in a language lost to time, encircle the orb, pulsating faintly in response to the rhythmic hum emanating from within. The hand itself, weathered and moss-covered, rests upon a crumbling altar carved from obsidian, its polished surface reflecting the ethereal glow of the orb. Behind the altar, a vast cavern stretches into darkness, promising secrets whispered by the echoes of ages past. Best quality, intricate details, clean lines, eye-catching composition, soft tones, archaeological fantasy realism, capturing the allure of a forgotten power whispering from the depths of time, perfect illustration
