Gao

Gao is a remote terran Outer Colony in the Cordoba system that survived the Great War. While nominally under the administration of the Unified Earth Government, both the people and the colonial government of Gao maintain a strong sense of national identity and anti-UEG sentiments are commonplace. The planet's Montero region was home to a vast cavern system — in fact an artificial Forerunner construct designed to support the Maginot Line.
