Add a new Dynastic Rule called “Orbit Contents” with the following text:

Orbits can contain things other than shuttles.  These are tracked in the subsection of the “Orbit Contents” wiki page corresponding to that orbit.  If there is an Orbit without a subsection on the Orbit Contents page, any Shuttle may add an empty subsection to it for that Orbit.

The Orbit Contents wiki page is considered gamestate and may only be modified in ways allowed by the rules.

Structures are one category of object that an Orbit might contain. An Orbit can contain at most one Structure; if an Orbit contains a Structure, any attempt to add additional Structures fails.

Blank the Orbit Contents wiki page, then add “Io”, “Europa”, “Ganymede”, “Callisto” and “Other” sections to it.  Then add a subsection for each Orbit to the appropriate section.

In the rule “Shipping”, replace the text “If the Orbit Number of a Shuttle’s Orbit is 1,” with “Space Elevators are a type of Structure.  If a Shuttle’s Orbit contains a Space Elevator,”

Add a Space Elevator to every Orbit with an Orbit Number of 1.
