Hello!
So, I've done some more work and I've gotten the basic setup working.
The event about the Aztec's landing is now a choice:
You can either give them the province for a large amount of gold and a good artifact, however, your vassals will be displeased and the province will be converted.
If you refuse, things will pan out closer to the vanilla version:
You won't lose anything but the Aztecs will invade.
In terms of the invasion, it will be pretty much the same as in vanilla except that most of the event spawned troops will disband on peace. Similar to the Western Protectorate, the Aztec Colony will request reinforcements if it has less than -50% warscore.
Should you get defeated by the Aztecs or you voluntarily swear fealty to the mighty Huehuetlatoani, then there is a decision for you:
As long as you're not zealous you can embrace the Aztec gods. This will also mean that the Huehuetlatoani won't have a revoke reason on you (The colony has the religious revoke law).
The Aztec is no longer pagan, but Mexhicatl, a separate group that will eventually include Mayan and maybe Incan (This is also why the Aztecs aren't using the Pagan UI or title graphics, though this will apparently be fixable in a future patch.) It currently has a head of religion, the Head of the Eastern Cult of Huitzilopochtli. The Huehuetlatoani of Tenochtitlan is the Head of the Cult of Huitzilopochtli, however, he cannot administrate the east so the power is delegated to the Huehuetlatoani. At the moment the head of the religion can't do much other than call crusades, but eventually, he will have special interactions that he can take. I may also make the Aztecs use the patriarch system, though I'm not sure how well that would work.
The mod is still not really playable, but it's getting closer. I hope to be able to release it Soon™. I still need to make the Aztecs interact well with everything and get the offmap interactions and events working/made.
That's it so far. Stay tuned for more.
