Create a rule called “Wide, Empty World of the Damned” with the following text:

There exists a number of Locations, which consist of a name, optionally a description which is flavour text, optionally a prerequisite, and optionally some rules text. Each Demiurge has a publicly tracked Current Location, which is one of the locations listed in the Locations subrule of this rule if that subrule exists, or is the location “Lost and Alone”. The default starting value for Current Location is “Survivor Camp” if it exists in the Locations subrule. If a Demiurge ever has a Current Location that does not exist, or has no Current Location, it is considered to instead be “Lost and Alone” and any Demiurge may and should set that Current Location to reflect that value.

As a daily action, a Demiurge can perform the Journey atomic action, which has the following steps:
The Demiurge must declare the Location they are Journeying to.
If they currently meet the prerequisite of the Location they are Journeying to, or if that Location has no prerequisite, they then must change their Current Location to that Location. Otherwise, they must change their Current Location to “Lost and Alone”.

Create a subrule of that rule called “Locations” with the following text:

The following are the list of Locations.

Name: Survivor Camp
Description: The remnants of humanity have banded together here. Out of the billions that humanity once boasted, now only a few dozen remain. Little food remains, and those that arrive must show that they have their own means to survive.

Name: Lost and Alone
Description: The dust storms are strong here, and visibility is low. Perhaps you can find a path out of here, or perhaps you’ll perish.

In every place where the term Demiurge was added to the ruleset by this proposal, replace it with the current term for Player should that term not be Demiurge.
