Exploration is required, Ben volunteers and leaves through the doorway. Time passes, Ben returns crawling with a bloody leg and faints.
Selene wants to go back, but if the elevator controls are tried, they do not allow ascension.
Selene is told to look after Ben. We leave to follow the bloody trail left by Ben’s leg.
The trail ends abruptly at a collapsed hallway not far from the hub.
Nearby is a lever locked behind a chain-link fence. Red lights.
