(this is a Countryhumans Universe)

it's a normal day in our time, each Countryhuman is peacefully minding their own business in their Country's Seat of Government (Royal Palace, President's House... Whatever it is). When suddenly... Them, their Current Leaders and all the various Past Countries' Ghosts appear in their Country... But in the 1700's!

(if you need an example: Austria (with the Hasburg Monarchy and Austria-Hungary's Ghosts) will end up in Vienna with Francis I and Maria Theresa)
