Season 3
When Ford Corvin defeated Tartarus on the grounds of Clearwater Community College he was unaware that his act of self-defense would have consequences on a cosmic level.
Ford was cryptically warned about Chaos and the Primoridals by the Bulletproof Bangs, the young seers of the student body, through an engimatic image of an individual (Ford) against a background of the sun which is consumed by a dark, black hole in the sky.
It wasn't until he met with Huitzilopochtli that he gained a better understanding of there being something beyond the solar system that threatened Earth, and the Pantheons, with apocalypse. Though his knowledge of the Primordials is skewed through the prophecies of the Aztlanti, he had the best knowledge of the threat that they posed of all the Houses. Huitzilopochtli said that a 'seal' had been broken, which had previously kept the 'great reckoning' locked away. Seeking to face the primordial's apocalypse head-on, as a test of his 'magnificence', Huitzilopochtli sought to work together with Ford. As such he was unwilling to cause the closure of the portal that had opened up.
