Keres drops the Wings Dive artifact.

In Greek mythology, the keres were spirits of violent death. Thousands of them haunted the battlefields, squabbling among themselves like vultures as they ripped the souls from dying soldiers. They craved blood and drank it thirstily from the torn bodies.

Keres were portrayed in art as pale ugly hags with wings, fangs, and talons.*

This trophy was added to the game in version 1.69.
