Add a new rule called “Doom Clock”, and give it the following text:

The Doom Clock is a publicly-tracked integer with a valid range of 0 to 13 inclusive, defaulting to 0.

If the Doom Clock value is ever set to 13, the value cannot be changed unless this rule is repealed.

Any time the Doom Clock value changes, the following steps are carried out by the Narrator according to the new value of the Doom Clock, if the value is listed in the table below. The default is to do nothing.
