Imagine an imposing demon, with reddish and scaly skin, with eyes shining bright yellow. His figure is muscular and tall., with curved horns extending from its forehead. He wears dark armor, battle-worn, and in one hand he holds a huge, ancient and menacing-looking sword, with runes engraved on the blade that seem to glow with a dark glow. His presence is intimidating, casting a long, ominous shadow over the rocky, arid terrain on which it stands.
