Try to follow Mirra
From Create Your Own Story
The tunnel snakes ahead of you. You creep stealthily through the twists and bends. There is no sign of Mirra, she is clearly at least as good at hiding her tracks as you are. Scans with your goggles and sonar reveal nothing. The passage seems to end in an abandoned control room. Relatively positive that you're alone, you approach a computer terminal and attempt to activate it. It seems to be functional, but needs a power source. Looking around the rest of the room, you see what looks like a power outlet in the wall as well as a back-up generator.
