A powerful dark mage stands in a desolate, ancient ruin, surrounded by swirling shadows. His blackened robes ripple with arcane energy, and in his outstretched hands, a luminous, fiery necromancy spell erupts. The flames are a vibrant green and orange, spiraling with glowing skulls and tendrils of smoke. The ground beneath him cracks, glowing with molten energy as skeletons claw their way to the surface. The mage's face is illuminated by the eerie light, revealing intense, otherworldly eyes. 4K, masterpiece, ultra-detailed, with a haunting and epic atmosphere
