Keres These carrion daughters of Nyx were the vile and rapacious spirits of violent death. Like the Valkyries of Norse and Germanic myth they collected the souls of warriors killed in battle. Unlike those benevolent warrior goddesses however, the Keres did not escort their heroic souls to the reward of a Valhalla. They flew from bleeding body to body, greedily sucking up the blood that flowed from them; then, when each corpse was thoroughly drained, they threw it over their shoulders and moved on to the next.
