I say the birth of a new generation, but is it really? As the child of Rhea and Cronus, she is in the line of Nyx, Gaia, Uranus, and so forth, but many of the other first generation Titans had already had children by this time. Just a few weeks ago we saw Atlas and Prometheus at play. She’s not even the first of the Olympians, for Aphrodite, daughter of Uranus, is really the first of the Olympians.
What makes this moment different is the impact this birth would ultimately have. Atlas and Prometheus and the many other titan children, some of which we’ll meet this issue, were the continuation of the Titan line and Titan rule. They were loyal to the preceding generation. There is very little written about Aphrodite during the reign of the Titans, but she doesn’t seem to have had much of an impact till much later.
The children of Rhea and Cronus are the ones who would ultimately end the age of the Titans and create a new world.
