How are you supposed to know somthing that wasnt explained in the full game.
So then you have to take a wild guess as to the made up **** that everyone else decided that it was to think like a nomad ect ect.
According to the story, they are drones, simple minded drones, they are controled by overminds and only think on a scale that is neccisary.
think of them as ants, they are contolled completely by pharamones and the behavior to follow all those cues from birth.
You think the uh... whatever that old race was called... would they give an organic defence ship thought? no, they just want it to protect the stupid empire, not have philosophical discussions with its "buddys".
If someone is going to RP as a nomad, they only need to do 2 things
1. shutup, don't say a thing, ask no questions.
2. follow orders from the one roleplaying as the overmind.
