In the rule “Rooms”, add the following bullet to the end of the list after the text “Every Room has the following qualities:”

* A string value named Circuit Breaker where the valid string values are “On” or “Off”, defaulting to “Off”

Add a new Dynastic Rule to the Ruleset. Call it “Electrical Panel”, and give it the following text:

There is the Electrical Panel in the Banewood Mansion, whose Location (which is a Room) is publicly tracked and is set to the value “Unknown” by default. During the Mansion Phase, the Narrator may set the Location of the Electrical Panel to an existing Room only if the current value is “Unknown”.

If an Explorer is in the same Room as the Electrical Panel, they gain access to a special Ploy named “Flip Breaker X”, where X is the name of an existing Room. “Flip Breaker X” requires light.

When executing “Flip Breaker X” as a Planned Action, follow these steps:
* If the Circuit Breaker value for that Room was “Off” at the beginning of the Mansion Phase, change it to “On” and add any light source name at the Narrator’s discretion to the list of Light Sources for the Room
* If the Circuit Breaker value for that Room was “On” at the beginning of the Mansion Phase, change it to “Off” and remove all of the names that are not names of Items from the list of Light Sources for the Room

In Banewood Mansion, set the Circuit Breaker value to “On” for every Room that has at least one name in its Light Sources list that is not the name of an Item.
