Space wants to be lawless, but some men have other ideas. The Grand Admiral is a commanding presence in the Terran Star Navy, and a man whose influence can be felt from Mercury to Pluto. Tasked with securing the Inner Belt, the Grand Admiral has the riches and resources of Terra at his disposal with orders to ensure order is maintained within the Sol System. While there are none more experienced in pursuing the fool's errand of attempting to secure the swirling vastness of even just this one little speck of outer space, it is inarguable that this pursuit takes its toll on a man- the Grand Admiral is a gravely serious and a seriously-aggrieved personality, bearing a long grudge from an incident twenty years ago. He has no mind for fairness, as he believes the universe likewise lacks this quality. That which has been built must not be disrupted, and those who would make prey of Terran interests must be brought to heel. These are the guiding principles of a man tasked with the impossible.
The Grand Admiral understands the limits of his power; there are simply not enough ships nor men to command them to cover every inch of Solar space. Light speed is a hard limit which cannot be met or exceeded and while specific regions of space can be identified and patrolled you cannot be everywhere at once, and like mildew in an unventilated shower block, lawbreakers turn up in every corner imaginable. Beyond that, his jurisdiction ends at the Asteroid Belt, with the Outer Belt falling under command of his Neptunian counterpart. His solution within his known limitations of controlling space was to set up the bounty system. By harnessing Terra's most potent resource- abundant wealth- The Grand Admiral can maintain a list of outlaws, bandits, pirates and thieves, assign an amount of credits to their capture and let the law-minded people of all of Sol's many worlds do the hunting in waters beyond his own authority. Greed is the path to bring law to the lawless and it is the most potent weapon in his arsenal.
It used to be a bounty hunter needed to be licensed, to be an agent of the court, but since there is no unified body of government covering all of Space it's hard to maintain that sort of rigorous filter if your desired goal is to reach the unreachable, so the Grand Admiral does not require the filter of licensure on his bounty hunters. A number of local offices maintain bounties on known outlaws, and if those bounties become large enough they get passed along to the Grand Admiral, at which point an outlaw makes the Big Time and draws the attention of seasoned hunters looking to put some significant zeroes on their credit chip. There are tiers to the list- at the lowest level you have bounties out for the unknown, for information, like a band of interplanetary thieves who elude capture on camera or description, or an unknown party responsible for smuggling illicit goods past the most rigorous security meshes- these are criminals who cause big problems for big powers consistently but without a name or a face it's hard to track them down, they make the Grand Admiral's list for the scale of their criminal activity but they're generally at the bottom. At the top of the list, well. At the top of the list you find those criminals who have personally aggrieved the Grand Admiral himself.
It was about thirty years ago, Terra sought to follow up on the success of the Titan Garden project by setting up a Venusian Garden and, later, a Mercurian Garden. With the help of Neptunian knowledge shared during the development of Titan Garden Terra learned it's possible to terraform these two smaller, more hostile planets, bringing their atmospheres more in line with their own perfect blue marble and opening the planets up to large-scale commercial trade. As it stood Venus was too acidic for non-Venusians to weather, lacking carapaces or regenerative properties, and Mercury was simply too hot, sweltering even in their underground tunnel network. Setting up more Gardens as footholds towards terraforming these worlds was in everyone's shared interests, believed Terran leaders, and it was the Grand Admiral who would oversee securing a site and transporting material and construction droids to see these projects through. This was, unfortunately, the high water mark for the Terran Curse of Arrogance, and the response it produced was a violent and tenacious band of criminals who would come to be known as the Devil's Fang Pirates, biting the hand of Terran influence off at the wrist and halting these new Garden projects altogether.
What started as a small nuisance grew into an enormous conflagration, one which the Grand Admiral had not initially taken seriously but which spiraled out of his control and by the time he took notice of the outlaws it was too late. His focus shifted from overseeing the Garden project to hunting and fighting tooth and nail with the Devil's Fang. Under pressure to resolve the issue quickly, after ten years of fighting he offered to parley with the pirates' captain, who initially agreed but upon meeting simply shot the Grand Admiral through the eye and took command of his flagship for herself. It was an embarrassment, the Grand Admiral survived the encounter but it also sparked the entire Terran Navy, every ship of it, to be deployed to squash the Devil's Fang once and for all. The pirates would narrowly escape being so outnumbered and disappear, heavily damaged, into the Asteroid Belt, presumed dead or disbanded as they had not been seen in Terran space for the next twenty years. The damage they did was done, the Garden projects were abandoned and the Inner Belt's hostile little climates remain inhospitable to all but the hardiest outworlders.
The Grand Admiral was held singularly responsible and demoted for his failures, and he'd spent the next twenty years working towards restoring his title. It was only the recent reappearance of the Devil's Fang that really made the case for his restoration, as previous Terran admirals struggled to face the lawless relics from an age long-past. With an old-fashioned chainsword on his hip and a plasma caster on his belt, the Grand Admiral prefers the hands-on approach to securing Terran space and while he would be happy to see anyone collect the Devil's Fang bounty, he would prefer to handle that job personally.
