Ilmater

Ilmater, the Iron Goddess, is the deity of endurance, perseverance, and martyrdom. She is most commonly worshiped in the fiefdoms of the Saltbrine Coast, particularly Lindor. Sister of Euphrosyne and daughter to Erebus and Nyxe.
Most often Ilmater is depicted as a winged weeping woman, made of iron. Her symbol is two hands bound together. She's also known as the mother to Phobos and Diemos, minor deities of fear and confusion, respectively.
An order of all-female warrior nuns known as Iron Widows are her most prominent followers. Its numbers are made up of women who have lost their spouses. Other names for the priestesses are the Wives of Ilmater or Sisters of Suffering.
