Kokuryu City

Kokuryu City. That's what Ender's Former Realm is now. A seemly endless metropolis bristling with skyscrapers, buildings, subways and all other things a city has. Kin Iramasha's army now resides around a huge chunk of land that resembles an island the size of large nation and floats, in what seems to be, a sea of endless purple sky that leads into nothingness. (So I suggest not flying off this island if you can't fly or figure a way back up) The landmass also has hundreds of black portals above it, that made it easy for Ender's soldiers to get wherever they need to be in the Human world or spirit world when Ender was still alive. The only accessible way to enter this place is if you know directly where this dimension is and know how to open a portal into it, you follow somebody into the portal that leads into this strange world or you think up you're own way into this base.
