Muscular male, bugbear warlock, fierce eyes, sharp teeth, dark brown fur, black horns, glowing red eyes, intricate tribal tattoos on arms and chest, worn leather armor, torn cape, grasping a staff with glowing purple runes, standing in a dimly lit, ruined castle, surrounded by old stone walls, overgrown with vines, mysterious fog creeping in, eerie ambient lighting, cinematic composition, dramatic shadows.
