In the aftermath of the Battle of Demeter, the IMC Expeditionary Forces retreat deep into Frontier space to regroup. On an uncharted planet, they begin constructing a new fleet operations base, drawing on newly acquired water collection infrastructure to support it. When drainage operations uncover ruins of unknown origin in a swamp near the base, Spyglass activates an archaeological team to study the site. IMC pilots use simulation pods to maintain combat readiness while anticipating Militia raids patterned on prior engagements at Angel City and IMC Airbase Sierra.
