In a dimly lit cavern, cloaked in swirling shadows, a dark mage stands before a circle of flickering candles. With a raised staff, he summons menacing shadow creatures that writhe and twist, emerging from the depths of darkness. The air crackles with energy, illuminated by occasional flashes of eerie light, casting haunting silhouettes on the stone walls. Wisps of fog slither around his feet, amplifying the foreboding atmosphere of his powerful incantation.
