Vatican

The vatican survived the apocalypse by building a dome over the city with nanites. They intentionally uploaded their consciousnesses and then infected themselves with nanites. Effectively giving themselves CFD and downloading their own E-ghosts into themselves.
The city is ruled by Pope Innocent XXIII. He is the general of an army, the Knights Templar. The Sylvestrines left the order over it and wander the world.
