As Reva peeked through the hatch she could see that the portable generators were attached, probably magnetically, to the ceiling of the hallway at intervals.  They were small circular devices with a light on the end and a narrow cable plugged in each side.  The cables ran from device to device, connecting them for as far as she could see through the hatch.  They looked like basic survival gear, off the shelf type stuff that probably didn't have any special functionality beyond maintaining an atmosphere and providing light.<br/><br/>The hallway was ten feet wide and roughly ten feet tall, probably a central corridor that ran some length of the ship.  The corridor was beneath the hangar and, given that the hangar was open on the front, any stairs or lifts up would be aft or to the side.  A peak aft, at least as far as she could see without opening the hatch further, revealed a number of corridors branching off the main hallway.  One of them, maybe thirty feet aft, lacked the telltale shimmer of the force-field.   There was no sign of an enemy or alarm, but she could only see a small fraction of the corridor.
