'''Stronghold Class Commerce Vessels''' belong to the [[Demiurg]] and are extremely well powered, large, and advanced. They are factories or ore-processing vessels and are often bases which move between systems and asteroid belts. They are also bases for a fleet of inter system asteroid mining pods, haulage flyers and prospector probes. Strongholds are often seen in uninhabited systems with fleets of small ships moving resources to and from the vessel and a planet or asteroid, with the prow facing the star. Most of the time the vessel will disengage if challenged but some will attack with a dangerous ferocity.
