In a dimly lit, ancient forest, a powerful dark mage stands at the center of a swirling vortex of shadowy energy. Clad in tattered robes adorned with arcane symbols, he raises his staff high, summoning eerie, wispy creatures that emerge from the darkness. The moonlight casts a haunting glow, illuminating the intricate runes etched into the ground around him, as the air crackles with an ominous energy.
