"This particular gang is called the Red Rovers," she explained, pulling up a map to show the particular area.  "Their hangout is the northern end of the harbor, most of which hasn't yet been rebuilt after the last Great Quake."  The map zooms in as her finger points.  "Their main base of operations is in this warehouse, which has most of its structural integrity remaining.  Details are a bit sketchy, but we can provide estimations as to the building's layout."<br/><br/>In the center of the room, a three-dimensional blue-white image materializes into view, much of it hazy and indistinct with uncertainty.  In some areas, green lines provide possible walls and suggested layouts, although those green lines have shown themselves in the past to be less than reliable.<br/><br/>"Over the last two months, the group has been getting bolder, sending away construction workers and attempts to rebuild, hiding from the police and scattering like roaches whenever larger numbers come into play.  This new weapon, however, could be just about anything.  No radiowaves were detected, and no explosive device can be seen at the point of the eruption.  Although we have theories, making a dozen such suggestions would serve no purpose."<br/><br/>She pauses briefly.  "It's entirely possible that this attack was a one-use-only thing.  If so, one of their number should be able to explain what they did and how it was achieved.  I trust you'll have little difficulty in 'persuading' one to tell you."
