A menacing armored demon cloaked in black and crimson, wielding dark magic; his head is a swirling orb of fiery energy, radiating malevolence. His chain-linked armor gleams ominously under ethereal light, each link a testament to battles fought and victories won. Dark shadows dance around him, conjured by his command of the arcane. His presence is a fusion of otherworldly terror and regal authority, reminiscent of an ancient evil from mythical realms akin to Lord of the Rings and Dungeons and Dragons. Rendered in exquisite 4k ultra-realistic detail, as if birthed from the capabilities of the latest Unreal Engine, this dark sorcerer exudes fear and power, an embodiment of dark fantasy.
