Oizys
In Greek mythology, Oizys, or Oezys, is the personification of pain or distress. In Hesiod's Theogony, Oizys is one of the offspring of Nyx, produced without the assistance of a father. Oizys has no distinct mythology of her own.
According to the Roman authors Cicero and Hyginus, "Miseria" is one of the offspring of the Nox and Erebus.
