I have been tasked with investigating certain freelancer Leon from freelancer group known as 'Starfliers'. Brief conversation with him proved to be rather useful in partly shedding light into his operations.
Group is made from freelancers known as Leon, Albert and Scotty operating a sirian civilian light carrier known as '\S/'NX-01. Then there is another freelancer named as Halpert and he is flying sirian civilian 'Starflier' fighter designated as '\S/'Silverstone. According to their manifest, both vessels are unarmed and without any significant armor plating.
Their main business is centered around star system survey and gathering coordinates for jump drives. They claim to be neutral and are willing to provide these services for anyone interested - be it lawful, civilian and criminal entities of any allegiance. Their rule is to not cooperate with nomads. They are adamant in keeping their client identities safe and are not even willing to share name of the client's organizations. It is safe to assume, some of these organizations are enemies or undesirables in the Gallia.
Their base of operation is located in the Kepler system.
In conclusion:
Directly - they are harmless civilians and researchers. Their vessels are not armed and are lightly armored. They are cooperative towards authorities in most ways.
Indirectly - their survey and mapping services can, and are used by unknown number of criminal and hostile organizations to the Gallia. As they keep their clients secret - it's hard to estimate extend of these operations. Even if they do not wish to cross any local laws - these potentially hostile entities will clearly profit from these services.
