A stylized, battle-scarred dragon with a rugged and imposing presence. Its thick, scaled hide is reinforced with jagged, black bony plates and sharp, protruding spikes. A tattered, crimson membrane stretches between its powerful, metal-chained limbs, forming a dark and menacing wing. The base of its form is heavily armored with sharp, uneven black bone, giving it a brutal, fortress-like appearance. The overall design is dark, powerful, and fitting for a fantasy or war-torn setting.
