What event is triggered when there are no Players in a Place, but Players are still on the server?

I didn't explain my question last time, my apologies. Let me try to explain a bit better:

Assume there is a Lobby as a starting place and a Gameplay Place that players are teleported to to play a game. Once a game is completed, players are teleported back to the Lobby. As there are no more Players in the Gameplay Place, is there an event that is triggered, other than checking with Players.PlayerRemoving, that the Place is now empty?

Please note in this example that the Lobby and Gameplay Places are part of the same Game. There are still Players connected to the Server, but one of the Places are empty.

I am under the impression that two Places can be under the same Game, therefore, the same Server. By this logic, two servers running the same Game with 2 Places will have 2 instances of each Place. Please let me know if this is true.

Also, what happens to this Place once it is empty, but there are still players on the server?

Thanks
