To properly model what you’re describing you can think of a coherence World as synonymous with your game’s continent, so you would start 2 worlds each with their own sim that cares about that world: one for each continent. You would then use a graceful transition, e.g. by opening a new connection to the new world and then closing your connection to the old world, between the worlds based on your characters location in the game. In this scenario as the character transitions the simulators sees them on their world and can simulate them.
The same concept can be used to transition players from worlds to rooms.
