Shhhh, don't summon her.
Anyway, Antarctica will be Southern Suharu. The whole of Suharu will fall under the direct responsibility of the Grand Highlord Supreme; Eastern, Middle, Western and Southern Suharu will each have a Grand Highlord appointed by the Grand Highlord Supreme, who will be directly responsible for the whole region. Each former state will function basically as a democracy, details are still to be worked out. There will be 100% free movement all over Suharu teritorry, so anyone who wants to live in Southern Suharu can move there at any point without any extra documents. Going to the other 6 nations will be harder though. Or easier, depending on how much you piss off the Grand Highlord Supreme. Some of you may even get to visit Former Australia.
