Ok I'll be the first to admit I have a bad memory. Can anyone tell me if the wraith have a world that they populate? Or do they just live and travel about the galaxy in the hive ships. How do they reproduce? Where are they building the ships at? If these issues were brought up I have a few ideas on how to deal with the wraith. No transportation= less threat. That would make for one hell of an episode i think.will we ever find out what message the aurora was carrying?
