A fearsome demon clad in intricate, dark armor, its chains clinking ominously with every movement, wields powerful dark magic. This malevolent figure is draped in flowing black and crimson cloaks that flutter as if whispering secrets of ancient sorcery. Instead of a head, there hovers an incandescent orb of crimson energy, pulsing with otherworldly life. The scene is rendered in stunning 4k ultra-realistic detail, as though conjured by the artistry of the Unreal Engine, evoking the grandeur of both Lord of the Rings and the thrilling mystique of Dungeons and Dragons.
