And the fog starts to clear...<br/><br/>I'm not 100% sure... but I'm starting to see what's going on.  This is a Scooby Do plot!<br/><br/>They're using a holographic projector... and using the nebula itself as the giant fog cloud to project the ghost pirate ship onto!  (if anyone HASN'T seen this particular Scooby Do episode... then you are probably younger than me.)<br/><br/>I don't know if it's really the old Imperial / turned Chaos / cruiser that the Katana first saw... or what.  But I'm betting that the "smaller" ship is some sort of speedy frigate with, say, one or two weapon systems that has been using the projected holograms for cover... perhaps it is a focal point for the hologram.<br/><br/>But the real foe... the one creating the holograms, is elsewhere.  Not that there isn't a ship with a gun that can hurt us if we let it get shoot us right nearby... but the faraway one, that's the one that's the real trouble.<br/><br/>Or at least, that's my theory.
