Hell's Gate/WMG

The rumored third civilization will be...

 * One based on Raygun Gothic ala Flash Gordon/Buck Rogers
 * Uh, 21st century Earth sounds pretty likely. Granted, we got nukes and outpace both civilizations in terms of logistics but two other civilizations may have secret equivalents or develop them rapidly. Alternatively, they might join forces if Earth outpaces them too highly.
 * 21st century Earth is unlikely, if only because they'd run ripshod over both sides. Dragons vs F22 will not end well for the dragons, and the sheer, hilarious degree of aerial superiority that modern earth would have over both sides, coupled with armor, missile artillery, IFV and infantry weaponry, and drones, means that both sides will get plastered in short order. Even World War II Earth would have a massive tech advantage over both sides to the point of total domination.
 * Though the Catharsis Factor of watching the arrogant and brutal Arcanans get utterly stomped by modern weaponry would be deeply satisfying.
 * It'll probably be some mix of 40k style tech (blocky, imposing, and tough as nails) and modern asthetics (Ipod, etc.)
 * My Little Pony Friendship Is Magic. Why not? It's invaded everything else.
 * Maybe a mix. Weapons tech somewhere around late WW 1 (so combustion engines and early planes and tanks) but with other aspects of the technology somewhat further advanced (maybe even computers). That would put them on a similar military footing to the other two but give them a logistics edge to help counter their total lack of talents or magic.
