Add a new Dynastic Rule to the Ruleset.  Call it “Communal Stats” and give it the following text:

There exists a row in the GNDT labelled “Community” that does not correspond to a player.  Instead, its columns track certain gamestate values defined elsewhere in the rules.

The Community’s Stamina value is equal to the current Food and Water.

If there is ever a Survivor named “Community”, the leader shall choose a new name for the “Community” row of the GNDT and change all instances of “Community” in this rule and its subrules to the new name
