Might aswell post my idea below.
Basic idea for the concept is a freelance for hire group, that works only with cover operation type work. They are however shady as they area to take any sort work of that type, no matter if its stealing or murdering somone or spying on one. The idea is they serve one one else but the group itself, do they simple contracted by the group and work out of said contract. Operating out the underworld per say of Valenwood.
