Reimu found the back door not only unlocked but almost falling off the hinges.  Cringing as the door squeaked as it opened, Reimu poked her head inside.  It took a moment for her eyes to adjust to the dim light, but she was glad that she'd tried to be stealthy.  Several imp packs snoozed in the large open area.  Reimu was silently thankful that her armor, scale and chain, was so expertly made, it did not clink or rattle as she entered.   Obviously she could take on the entire mob of imps, there were easily twice as many as the cave where she'd rescued Ana and Scriz, but there didn't appear to be a large leader either.<br/><br/>Looking around the gloomy factory she saw the ruins of several machines, some with rubber hoses rotting off and some with no discernible function, but all completely junked.  Towards the front of the factory there seemed to be a large door leading to a different part of the factory, but there was also a rusty and rickety metal staircase leading up to a second floor of the factory.   A quick visual inspection didn't show much else, but there might be all sorts of interesting things hidden in the rubble.  Of course, it might be difficult to scrounge without waking the imps.
