In a dimly lit cavern, a robed dark mage stands at the center of an intricate circle drawn with glowing runes. Tendrils of shadow swirl and twist around him, taking shape into menacing, ethereal creatures with glowing eyes. The air crackles with dark energy, as an ominous mist fills the space. Surrounding stones are etched with ancient symbols, pulsating softly in response to the sorcerer’s dark incantations, creating an atmosphere thick with power and mystery.
