Hey, guys! I might be at work when the winner goes up so in case I win and aren't around to answer questions I wanted to write a small bit so people can start figuring out where they were during the events! It was a bit rushed since I only today realized Dragon was going to announce a winner soon, but hopefully it does the trick.
If you have any additional questions about clone behavior as pertaining to my entry (as it had really strong interpretations on their worldviews and temperaments) send me a PM or poke me on Skype! If my entry becomes canon and you want to stay true to it, however, a vague suggestion would be to follow about what they did in the story: they panic and go nuts. And being near fanatical, convincing them their worldviews are wrong is about as easy as being on either side of an argument between a stereotypical atheist and religious man.
Where was your region? If you like, it can be handwaved that your region had a small force in the Cerian army much like Sanctuare and Raoga. Just let me know first and we'll work out the details together!
The UR, unfortunately, had a bit too many legendaries floating around to be within the scope of what I can reasonably handwave into the background; my entry works under the assumption that [the UR] took too long to arrive since they were waiting on several regions to finish manufacturing equipment to outfit their soldiers - I believe there were posts describing this - whereas Ceriah already had its armory stocked ahead of time.
To be clear, no one arrived before Mewtwo and Ceriah/Sanctuare/Raoga arrived soon after. It's assumed the other regions (those who we don't end up retconning in) were on their way during the events of the entry. They presumably will arrive a day or so after my entry ends.
