In Due Time
The First Law
Toward the end of The Age of Creation, when Yhera had completed her work and was well satisfied by it, one of the mortal races commits a grievous crime. In grief and anger Geniche departs the world, and pronounces the First Law, the Law of Death: that all born of her Earth must follow her into the Underworld. With her proclamation, a part of the world became fixed, and Time was born.
Different cultures have different myths of the Crime that ends the Age of the Gods. Most believe it was Theft, Rape, or Murder: something that was taken, rather than received as a Gift. Geniche, Yhera, and Hathhalla curse the criminal with Horns as a mark of his crime, and ever since The Horned Man has been a popular scapegoat in myth and legend.
