Okay. So everything you just said in that first paragraph? Tooootally backs up the whole alternate dimension thingy. Especially since when I type "Esthar" into Google it brings up info on a fake country from a game. So. Um. Sorry, looks like you're probably just as fictional around here as I am. It sucks, but you get used to it.
It's not just a possibility, it's also the way it is. Alternate dimension, bucko. Get used to it.
