Leto has become pregnant with twins after a night with Zeus. However, Hera's immense fury leads to a curse that she cannot give birth anywhere on the face of the earth. Just as Hera decreed, Leto visits village after village begging for a place to labor, only to be turned away at every door. Now, she is running with her heavily pregnant body, pursued by a giant serpent sent by Hera, when she spots a rock rising out of the distant sea.
