Onaga's Wing is a large, dragon-like appendage with a wingspan that exudes power and menace. The wing features a leathery membrane stretched over a framework of sharp, bony protrusions, with a color palette of deep reds and blacks, accentuated by glowing orange veins that pulse with energy. The surface is rough and textured, resembling ancient, battle-hardened scales, with intricate patterns carved into the bone structure, symbolizing its draconic origin.
