- Interstellar Travelling (Travelling in Charted Space)
Interdictions must be approved by a member of the Imperial family, but generally such approval is given in response to a request from an interested service, nearly always the Scouts or the Navy. Interdiction may be imposed for any number of reasons, including to shield a military base or other sensitive installation, to ensure the seclusion of private reservations belonging to powerful families, to protect developing societies from interference, or to reserve valuable resource areas being saved for later development or exploitation. Enforcement of interdicts varies with the reason for the restriction as does the penalties for infractions.
Vulnerable Society Shielding
It is generally held that the Scouts mostly recommend interdiction to shield young or sensitive cultures from the interference that interstellar trade and commerce will bring.
The Navy is held to be more vindictive in its recommendations, using interdiction to punish local governments.
Interdicted worlds usually have no starports at all. However, in some instances the interdict only applies to outsiders, local inhabitants being free to come and go as they please. In such cases there may be a starport serving the needs of the locals.
The Imperium’s practice of interdiction of worlds for diverse reasons has long been a source of contention between liberal and conservative factions in the government.
Travellering Society Travel Warnings
There are few other polities able to interdict worlds, but when it happens, their policies tend to be similar. For instance, the Zhodani Consulate actively interdicts some of their Forbidden Worlds, for reasons any Imperial naval planner would recognize.
