They do not work for the Nomads. If they did, they would have infested all of Sirius by now. They go willy-nilly around the houses with no restrictions. Why? Because they are no threat to humanity, they just have their own beliefs, be them religious or otherwise. It's like the old practice of killing someone who worships a god with a different name from yours. Or killing someone because they looked at you wrong, or said something you didnt like. You engaged them on the belief you thought they were assisting the Nomads, but yet you yourself have no proof that they have had contact with Nomads, let alone assisted them with anything. If you wish for yourself to be useful Karlotta, you should remain out of Liberty. I've seen your actions before. You've engaged me without warning LONG before the Oracles appeared.
Remember that one time, long ago, I was a Lane Hacker? I was flying a Broadsword and said "I think it would be a good idea to get out of Liberty, it's dangerous for Order here." Does that ring a bell? How about when you fired lasers and missiles in my face four seconds after that? And then when I confronted you, it was apparently a threat. You've always been the one causing trouble Karlotta, alot more trouble than I've caused.
