Nomads...

[Rashnok]

Factions that I think would know about the Nomads.


Order
Outcasts
Corsairs
Bounty Hunters
LSF
LN
BAF
KNF
RM

Those are the easy and obvious ones. The first five or six have obviously had extensive dealings with them. All the militaries have also had to deal with nomads, after the big infiltration and nearly coming to war. I would expect, however, the knowledge to be relegated to simply the higher-ups.

The following factions may also know of the nomads.

Pretty much everything in Rheinland, especially the Red Hessians.
GMG - For some reason, I figure that they wouldn't exactly be strangers to strange things in space.
Zoners - Same reason as the GMG, plus their close relations to the Order, Outcasts, Corsairs, and GMG.
Blood Dragons - As seen in single player.
Lane Hackers - As seen in single player.
Bundschuh - As seen in single player.
Junkers - Because, of course, they know everything.

I suppose we could also lump in the Phantoms and such too, since they are pretty much nomads in and of themselves.
