Down into the subway complex, the earthquake left a strong degree of rubble which had never been cleaned up.  Stores were left abandoned, and unpowered tracks lay bare, with only one of the tunnels remaining in order to guide a way further down into the maze beneath.  Emergency lighting flickered on at the approach of the agents, giving enough light to find one's way but leaving a strong degree of concealing shadows around corners and huge holes left by the earthquake so long ago.<br/><br/>Yet, far enough down, a light shone far more brightly than the others.  Something deep inside was projecting its own illumination, either in defiance of or predating the emergency lighting.<br/><br/>The soft, repetitive drip of a nearby leaky pipe gave its somber song.
