[[WMG: The rumored third civilization will be...]]
* One based on RaygunGothic ala ComicStrip/FlashGordon[=/=]BuckRogers
* 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 CatharsisFactor of watching the arrogant and brutal Arcanans get utterly stomped by modern weaponry would be ''deeply'' satisfying.
** Plus, they make a point of mentioning a volcanic eruption that can be assumed to be Krakatoa that happened 30 years ago or whatever in every world. So it'd be early 20th century, not 21st.
* It'll probably be some mix of 40k style tech (blocky, imposing, and tough as nails) and modern asthetics (Ipod, etc.)
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. Why not? It's invaded everything else.
* Maybe a mix. Weapons tech somewhere around late UsefulNotes/WW1 (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.
* [[SufficientlyAdvancedAlien Sufficiently Advanced]]
* How about a civilization with World War II era tech? Would have enough advantages to pose a serious military challenge to both existing nations while not being too overpowering. If they have nukes, make them plane dropped or give them very crude ballistic missiles like the V-2.
* ...Us. I mean, we're pure tech, no magic or psychics. Why not Earth of the 1920s? Sure, there wouldn't be MUCH difference between Sharonans and Earthlings, but we've got a bit of head start. Internal combustion was well on its way, we had tanks and airplanes and zeppelins. We have radio and telegraph. What could be more fun?
* It'll be [[MyLittlePonyFriendshipIsMagic Equestria]]. Why not, it 's bloody impossible to keep bronies out of anything else, why should this be any different?
