Collector Base

The Collector base is a massive space station located in the galactic core near the outer edge of a black hole. Home to countless Collectors, Seeker swarms, and Collector controlled Husks, it also houses the Collector leader. It can only be reached via the Omega 4 Relay and is surrounded by a vast debris field which several Oculus hide in. Able to survive being so close to a black hole to what Commander Shepard presumes is Reaper technology, it keeps at least one Collector Cruiser docked with it, proving its size due to the way that the base dwarfs the cruiser.

After Shepard discovered a way to safely travel through the Omega 4 Relay, he took his team to the base aboard the SSV Normandy SR-2 where they made it through the defences surrounding the station and eventually crashed on the surface of the station, remaining undetected due to the station lacking a security system due to Collector overconfidence that nobody could reach the station.
