Hephaestus

While Hephaestus was forging his life away in a hidden mountain like a cultivation master. The other gods dramas continued.

Zeus killed his wife Metis after he got visions that he be overthrown by a son born from her.

He did this by making her drunk and tricked her into turning into a tiny bird then eating her. And to make sure, she dies, Zeus use a new law that he understood after he become the third god king called the law of transformation.

He cut Metis's divine personality into two parts, the one that represented her and the one that represented the goddess of wisdom. He then devoured the 'Metis' part of her divine personality which allowed him to gain some wisdom authority. Since that 'Metis' is mostly known as the wisdom of Zeus, not the goddess of wisdom and wife of Zeus.

He also transformed Metis's divine soul and her god's personality and her divine body into an embrio of a god and put it inside his head. This cause Athena the goddes of wisdom to be born.

This act cause the other goddess to see a chance to become Zeus's new wife/lover. Hera with her wisdom and understanding of men and women made Zeus lust for her and tricked him into becoming her husband by telling him that she can only be with him if she became his wife. She also told him that she doesn't just want to his his wife but also his companion that will be with him till the end of time. This cause the first marriage to be born and with it Hera evolve her prieshood into the direction of promise and bond between men and women and became the goddess of mariedge. This also cause husband and wife and lovers to have two diffrent meanings.

The union of Zeus and Hera also cause the birth of Ares, the god of war and Hebe the goddess of healing.

While on Gaia's side, she manage to convince Atlas to join the four pillars plan by promising him to take care of his daughters after he became a spirit primordial since spirit primordials have their bodies fuse with world causing them to not be able to interfere with the world much.

She also manage to get Oceanus and tethys to join the plan. It was easy since by doing this, they can become truly one and become one of the most powerfull beings in the world.
