Reword the first sentence of Wide, Empty World of the Damned to:

There exists a number of Locations, which consist of a name, a Population Size (which is an integer defaulting to 0), optionally a description which is flavour text, optionally a prerequisite, and optionally some rules text.

Set the population size of the Survivor camp to 2, the Waterlogged Shops to 1, and every other location to the default.

Add a subrule of Ideologies called “Leader of the People” with the following text:

Each location with a non-zero Population Size has a publicly tracked Primary Ideology which can be any current or previously existing Ideology or can be blank (defaulting to blank).

Whenever all locations with a non-zero Population Size have the same (non-blank) Primary Ideology, that Ideology is considered to have Rallied the People against the Guardian.
When an Ideology has Rallied the People:
* If that Ideology has a rule denoted as that Ideology’s Election Mechanic, that Election Mechanic rule is followed.
* If there is no Election Mechanic for that Ideology, the owner of the Ideology has achieved Victory.
* If there is no Election Mechanic and the Ideology has no owner, a randomly determined Demiurge with that Ideology Allegiance has achieved Victory.
