Where is Evocity set?

[Emil]

Since its a fictional city, its probably not set anywhere specific. Though, we know it is probably in the U.S or maybe Australia (though the enviroment doesn't look very "Australian". I may be wrong, I ain't an Aussie). It could even be in Canada. But let's say its in the U.S. Since all of the city is blocked from the outside-world because of the mountain-walls, it's most likely located near mountains. Now, I dont know alot of mountains, especially in the U.S, so I wont make a guess what these mountains are.
Also, there are no coastline. Evocity is probably very far inside of U.S, so I wouldn't say California, but I dont really know.
