So Happy I Could Die
Spoiler Changes (need someone to do these!) :
Move about half of Montezumas attacking forces so that they surround Spanish cities close to (but not directly adjacent to) the Shrine of Heresy.
The other half of his army? Remove all of their promotions and add City Guard Promos. Perhaps remove a few of his soldiers. Reduce the size of all cities on the map (by 2-5).
Place three Cavalry with Combat I-VI and Morale and Mobility and Pinch and Ambush and Drill I-IV, named "Rider of the Apocalypse" - one should be on Aztec continent, at least. Attack AI.
Remove some of the celtic troops as well.
