Colossal Caves

Category:Anomalies
 is an anomaly in Starcom: Unknown Space 
Anomaly text: "This lander touches down in a broad glade not far from a large cave in a 50m cliff. As the team approaches, the cliff is revealed as the overgrown ruins of a Fallen Empire structure. The cave opening is an archway. There are clear signs that the interior has been modified from its original layout: some passages have been sealed off with large stone blocks."
