Separated by vast distances, separated by the void between worlds, no one knew everything that had happened in the Hemenu World.
On Mount Olympus, the King of All Gods had long forgotten that human female. Although still young among the deities, compared to humans, Io was just an insignificant detail in his lengthy life.

For Gaia was soon to awaken, and the throbbing from the Earth was growing increasingly intense. Only when both Apollo and Aphrodite had returned to their places before then, could Zeus's Sovereign Ritual be half-established. By that time, he would initially possess power surpassing that of all gods, confident enough to confront Mother Earth on Olympus.
In such circumstances, the existence of Io had, naturally, long been forgotten by him.
