Enact a new rule, “Artefacts”:-

Each Artefact has a Name, a Description, a Location, a Protocol and an Effect. Artefacts that exist are listed as subrules of this rule, with their Name as the name of the subrule. An Artefact’s Protocol may impose restrictions on how Individuals interact with it. An Artefact’s Effect defines what it does and how this may occur.

An Artefact’s Location may be either a Place, an Individual, or Unknown. If an Artefact’s Location is an Individual, it is said to be carried by that Individual, and the Individual carrying it may, for the purposes of any action they take, consider its Location to be their own Location. If an Individual shares a Location with an Artefact, they may set its Location to themselves.

Add a subrule to Artefacts called “The Pencil”:-

Description: A 19cm hexagonal HB pencil with a black-painted body and no manufacturer’s name. Its lead is sharp and it appears unused.
Location: Unknown
Protocol: None
Effect: An Individual carrying the Pencil may erase from the ruleset any Artefact (except the Pencil) that they share a Location with.
