History & Background (Dossier)

• Information about the system is limited.

There is normally no activity within the system.

• Commercial traffic is extremely rare: the system sees very few visiting ships.
• Commo only picks up natural background noise and static.
• The system does not have any commercial navigation beacons.

Note that social data, though only 40 years old, may be out of date: previously undocumented groups may now inhabit the system and maintain their own culture, forms of government, and systems of law.
