Create a dynastic rule called Explorers with the following text:

Explorers have the following tracked fields:
* Items, which is a field that can contain any number of Items that are defined by the rules. It defaults to containing no items.
* Location, which is a Room (as described in the rule Banewood Mansion). If either no rooms are defined or no default location for explorers is defined, Foyer is considered to be a valid room and is considered to be the default.
* Planned Action, which is as defined in Explorer Actions.
