From publisher blurb:
Wielder of the Astral Mace
Onyxe is an oread princess from the mountainous world of Slaat. Cast aside by her family in favor of her younger -- and beautiful -- sibling, Onyxe attempted to kill her sister during a violent outburt and was thus exiled. Years later, Onyxe returned armed with Zund’r the Astral Mace, and killed her parents, taking their place as ruler of Slaat.
When not ruling her world with a tyrannical fist of stone, Onyxe heeds the beck and call of her master, Typhon.
Super Powered Legends. Because sometimes what you need is a character everyone will recognize, even if they’ve never met her before.
