^Maybe the Volge don't have nerve gas either. Everybody is in relatively bad shape following the Pale Wars and the Arkfall, and the various Votan races are at a distinct disadvantage considering that they're refugees on someone else's turf. They only had what they brought with them, and a lot of that was no doubt expended in the wars and the initial Arkfall.
Hey, I just thought of that -- everyone's comparing this to older shows like Firefly
and even Babylon 5
, but the idea of alien refugees arriving in vast starships and having to assimilate with humans is reminiscent of the great '90s series Alien Nation
. The difference being that in Defiance
, even the humans are refugees along with everyone else.
