"Spearwomen walking the Path of Zerae are best given a wide berth, for they can be as violent and indiscriminate as the Twin Seas."— A veteran of the Time of Troubles(src)
Zerae is the Amazon goddess of vengeance and storms, and is Hefaetrus's wife. She prizes the Amazons devoted to her by giving the power to enchant their javelin and arrows with Lightning. The ones that are most devoted to her try to pass the Rites of Vengeance, and are even further rewarded.
A priesthood of Zerae exists, one with a high priestess.
