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

Each Shuttle has an amount of Fuel, tracked in the “Fuel” column of the GNDT. New Shuttles start with 2 Fuel or the amount of Fuel the Traffic Warden has, whichever is higher.

Each Shuttle may gain 3 Fuel as a weekly action.  Whenever a Proposal becomes Enacted, unless the Proposal’s text states otherwise, its author gains 2 Fuel.

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

There are four Moons, Io, Europa, Ganymede and Callisto.  Each Moon has an Orbital Size: 5 for Io, 10 for Europa, 20 for Ganymede and 1 for Callisto.

Each Shuttle has an Orbit, tracked in the GNDT.  An Orbit is a Moon (tracked as the first letter of the Moon’s name) followed by an Orbit Number from 1 to the Moon’s Orbital Size.  New Shuttles start in Orbit G20.

Add a new sub rule to the rule “Navigation”.  Call it “Restricted Area” and give it the following text:

Only the Traffic Warden may have orbit C1.

Set all Shuttles’ Orbit to G20.  Set the Traffic Warden’s Orbit to C1.  Set all Shuttles’ Fuel to 2.  The author of this proposal does not gain Fuel when it becomes enacted.
