Fuel
As you know, Liquid MacGuffinium (LMg) is the main source of fuel for all space travel in the galaxy. Now, in the space empires, the production and sale of LMg is highly controlled and regulated (after all, if you had enough raw MacGuffinium in one place you could blow up an entire planet). To refine and produce such an important resource requires an entire supply chain for extraction, purification, refining, and acid purging, in order to create the safe, fuel that spaceships need.
Rumor has it, that the Butcher King has a fully functioning, albeit less safe LMg production facility hidden in the asteroid belt of some far off system. This production facility is no doubt heavily guarded by <PERSON> loyal former legion, and indeed that is where you can find his massive dreadnaught.
Word is, even if some daring crew could gain control of the station, they wouldn't be able to run it. The only refinery engineers out there that know how to operate a facility like that are either part of the Imperial Navy or loyal to <PERSON>.
Thieves, pirates, raiders and vagabounds must either (dangerously) outfit their ships to run on raw MacGuffinium, spend all of their time raiding heavily defended LMg transports, or buy it from <PERSON>.
Fear
The Butcher King watches all. His eyes and ears are everywhere, and he suffers no traitors. The word is out: <PERSON> always gets his cut.
The evidence of those who hid their scores from the King are plain to see. There's the husk of the mighty pirate dreadnaught that was cut in half from space, orbiting that planet like a ghastly moon. Outside of the trading port, there lay a massive pile of heads from the last Raider crew who didn't pay the King his due.
Turn in your crew and you will be rewarded by the Butcher King. 963
Defy him and he'll send every Outlaw, Bounty Hunter, Assassin, and Saboteur in the sector after you. Or sometimes he'll just "accidentally" leak your ship's location to the nearest Imperial Cruiser.
Loyalty
<PERSON>? Oh man, he's the greatest. When you hear him talk, it makes the Butchers feel like they're not the scum of the galaxy. The empire might look down on bounty hunters and scavengers but the Butcher King? He protects them. He loves them unconditionally. He takes the people cast out by the empires and gives them a home. He knows the Empire, inside and out, used to run one of their legions. He knows that the butchers are destined for greatness. He's going to lead the butchers out of this forgotten sector of the galaxy and one day, the butchers are going to take back what's rightfully theirs. 503
