Ashen Poll: Future Locations

I want to patrol the European Dead Zone.

[b]FOR EARTH[/b] - Tibet, Lhasa. Aside from the cool Buddhist stuff, there is some interesting lore here about the Golden Age research on the FWC Device. - Africa. Would be cool if it had ruins of a high-tech Africa with metal pyramids that housed a now-dead warmind named after a pharaoh. - India. Ancient Hindu temples juxtaposed with skyscrapers and the wild. - I want t see the world beyond just familiar Western civilization, so I don't care about Chicago and [b]NOT EARTH[/b] - Europa. I like ice worlds, and the oceans under the ice could have all sorts of interesting mysterious life. On top of that, Europa is a Jovian moon, making it the territory of the Nine. Many clues in the lore actually point to something exo-related on there, so it might be the origin of the Deep Stone Crypt (DSC is a subroutine that seeded exo consciousness, and not necessarily an actual place. The fact that the exos dream of killing everyone they ever met there suggests it isn't real.) - Mercury. A Vex machine-planet part of an intergalactic network? Yes please.

Can someone explain what the first 2 are?
