So, do we know what's back there yet?
If not, I have some theories.
I think there's an intact empyrean city or something in there. Look at the highways. They aren't broken like the rest of the world. Also, its green and it doesn't look derpy green like the city core.
So, are we going to get to meet some empyreans? Will we just find dusky old tomes left by them explaining how to activate thier technology? Will we launch ourselves into worlds beyond telara once we retake and repair the city? Will it be like star gate Atlantis? Will we accidentally awaken some new evil by tampering with technology beyond our understanding, far worse than regulos???
EH.. I'M FREAKING OUT.
