The Keres (also known as Daemones) are battlefield spirits of famine and disease that feed on violent deaths and are polluting spirits. The Keres are daughters of the protogenos Nyx. In mythology, they were often found wandering battlefields. In later times, they were also regarded as the vengeful spirits of the dead. They live in the Underworld and had supported the Titans in the Battle of Manhattan, but didn't directly attack Olympus in the Second Olympian War.
