so in the example, they had 3 location authority server and 1 replication layer,
so each location server can represent a physical location on 3d world, say its own solar system, and moving out from location A to location B moves you to a different server, and that was possible cause your position matrix was store in the replication layer and each server has a copy of replication layer.
now how do you handle updating all those in realtime is what amazed me, they even have bullets go through locations
