Quarantined World

Galaxy Portal Planets

Quarantined Worlds are an Imperial classification of planet. These worlds are too dangerous to settle or explore, but still seen as too valuable to destroy or ignore completely. These planets are placed under strict quarantine by the Administratum or Inquisition and sometimes are even blockaded to ensure that nothing may enter or leave its surface until the Imperium can properly utilize them.^[1]
