Treason and Plot

Question: So I read in your fiction that Mixcoatl betrayed the Aztlanti and became a Titan. So why did he turn right then? Was it because doing it before the Titans escaped from Tartarus would have been suicidal?

The episode in which Mixcoatl begins his concerted assault on the Aztlanti appears in the story Drums of War, in which Sangria responds to her father's call to arms while Geoff is off learning uncomfortable truths about his Norse brethren. While we have had gods go Titan during game - Danu was one, since we already had a Scion of hers in play - Mixcoatl actually isn't one of them.

Mixcoatl was already a Titan in our game, and was locked in Tartarus with the rest of them. Why that was the exact moment that he fully roared back to ruin the Aztlanti's day is unclear; maybe he was late getting out of the prison, or maybe he was gathering his power and recruiting allies before making a head-on assault on the pantheon; Quetzalcoatl had recently been severely injured in an altercation with the Amatsukami and was mostly out of commission at this time, meaning that he wouldn't have been available to run interference between his father and his people. Whatever the reason, Huitzilopochtli and the rest of the pantheon were not surprised by Mixcoatl's attack. They had to have been expecting it to happen fairly soon after the sundering of Tartarus, and they weren't wrong.

Sangria and Huitzilopochtli both refer to Mixcoatl as a traitor because, from their point of view, he is the definition of one. He's Aztlanti by blood, the father of several of its gods and the maintainer of part of its universe, yet he is choosing to break every bond of sacred loyalty and duty to assault his own people and destroy the world they maintain. He is and always will be a traitor in their eyes.

Prior to Mixcoatl charging in to lay seige to Acopa, the Aztlanti were primarily trying to deal with Coatlicue, who was not being overtly dangerous enough for anyone to get away with hurting her for fear of being murdered by Huitzilopochtli, but who was also laying the groundwork to severely damage them in the future. With the all-out assault from the stars, however, almost all of the Aztlanti efforts have been turned to the war in the heavens.
