Make Peace or Die

The two men brought to the first century are beginning to change the timeline dramatically.
John, in North America, is reeling from the loss of his son, who was used as a sacrifice by the Totonac people, a people little different from the Aztecs that replaced them in our timeline. The Totonac people are reeling from the devastating losses the buffalo riders easily inflicted on them. John and his Trade Alliance have technology that is centuries ahead of anything the Totonac people have, but the Totonac people have a population that dwarfs the Trade Alliance. As the timeline continues to change, how will their conflict shape the new future?
Ever since Paul was brought back to the first century, he has been scrambling to make his young nation strong enough to withstand the empires of the first century. His nation's wealth has been noticed by the Himyarites, and they have decided to test his defenses. How will Paul’s young nation survive being attacked by a nation that has more soldiers than he has men?
