Background
This fearsome weapon is a huge, serrated axe with cruel-looking spikes jutting out from the top and back of the blade. Originally designed for orc champions, weapons of this sort have recently been found in the hands of tauren heroes, as well as members of the Burning Legion. Another version of this weapon lacks the serrated edges or the spikes, but has runes engraved across the blade.
