Kharum-Vor, the Battle God's Great Axe

A massive great axe forged from black adamantine and the fossilized horn of a primordial mountain beast. Its broad crescent blade bears seven deep notches, each filled with red copper and ancient tribal runes. The haft is petrified ironwood wrapped in braided beard-hair cords, bronze rings, and strips of battle banners taken from long-dead clans. When raised in anger, the axe gives off the sound of distant war drums, and faint ancestral faces appear in the metal.
