after a failed ambush nearly kills the players, the officer appears to be killed by the assassins for getting too close. The party is put back on the trail by a disguised Arrusif, who may also be anarchistic like these guys, but considers himself far more noble. They discover that the Freelancer officer was really a mole the whole time, using his position to eliminate up and coming Freelancers who might be a threat, and may even be the assassin leader. The players are asked to stop him by Arrusif.
And then basically awesome happens up until Arrusif takes something from the assassins that he needs for his ritual thing and takes off, thanking the players all the while.
