Greedy Hangmen

The proper name for the “Greedy Hangmen” assassins is not known. Their ability to kill people at any point, however, is well known. The “greedy” part of their moniker comes from their seeming inability to stop killing. Most assassins kill the target and leave.
But the Hangmen take unnecessary risks to keep killing. It’s caused them to eliminate two headquarters, three bridge crews and effective destroy a colonization attempt.
So far, no one has admitted to employing them.
Their last known attack was under the employ of Ember Nostromo. One of their bands was supposed to help in a double-cross, killing a bridge crew from the Coil Nebula during negotiations. As they began to kill, they could not stop. One of them attempted to strangle Ember, and she opened her warp eye.
