D4rk_f4nt4sy_illustr4tion, dark fantasy illustration in a hatched style, with thick lines and pronounced textures. A Nazgûl rides atop his black steed, both shrouded in darkness and dread. The Ringwraith is cloaked in tattered, flowing robes, his face hidden beneath a deep hood, radiating an aura of cold terror. He wears thick black leather gloves, arms armor and thick black spiky boots. The black horse is lean and powerful, eyes glowing faintly as it charges forward, its mane whipping in the wind. Shadows seem to cling to rider and mount alike, creating a chilling, ominous presence that embodies fear, death, and dark magic.
