Prompt:
masterpiece, best quality, fantasy art, dark fantasy, 1man, solo, A Duergar (Gray Dwarf) Slave-Lord War Commander overseeing his domain. He stands on a rocky outcrop in a vast, echoing mining cavern, a figure of absolute authority. His skin is like rough slate, his head bald and scarred. He wears formidable, spiked dark iron plate armor, meticulously maintained but unadorned, and a helmet with a glaring visor rests at his hip. His face is a mask of cold, calculating ruthlessness, with piercing black eyes that miss nothing. In one hand he holds a spiked, brutal warhammer, its haft resting on the ground. The other hand points with a gauntleted finger, issuing a silent order. Below him, countless slaves (goblins, kobolds, humans) toil under the whips of duergar overseers, extracting ore under the glow of harsh, magical lanterns. Atmosphere of oppressive tyranny, industrialized suffering, and cold, militaristic order. Style: gritty, hyper-detailed dark fantasy, dramatic top-down lighting, sense of scale and depth. (duergar, gray dwarf, warlord, commander, slaver, slave lord, plate armor, warhammer, bald, ruthless, mining, slaves, underdark, dark fantasy, tyrannical).
