History & Background (Dossier)

• The system was initial surveyed by the Terrans during the Interstellar Wars period, where it became the spearhead of exploration into Jardin (then known as Thalassa) subsector.
• Given the thin atmosphere of Sinnoch the Terrans deliberately recruited colonists from the Bolivian Altiplano, a high altitude area on Terra (world).
