A dark fantasy phone wallpaper of the death knight, holding his sword in one hand and surrounded by chains with skulls on them. In front is an endless abyss that leads to hell. The background has black smoke and flames around him. He wears red wings on each shoulder. His eyes glow like fire, and he looks menacingly at you while standing at full height. It's nighttime, and there is darkness all over everything. Portrait format. High resolution. Hyper-realistic. --ar 9:16 --s 50
