Giles has a base set up in Salem, MA, for whenever he needs to rest and relax for some time, other than that he wanders taking underground and black market jobs. He typically takes jobs within the US but if he needs to travel over seas he will do so as long as the pay is good and the job is within his sense of justice. If he didn't have his base in Salem he would prefer to settle down somewhere with bountiful farm land. He dreams of being able to relive his farming days with his live stock, but until then he will ensure the world's scum is dealt with. Reasonably of course.
Giles makes his money by taking jobs from the underground and black markets. He is essentially a hit-man but he only takes bounties on deplorable people, people Giles believes to be dirtying the world with their actions and motives. He will take jobs that free those that have been wrongfully imprisoned as well. He hates people in positions of power that are corrupt having fallen victim to their schemes in his younger years. He spends his money on preparations for his next jobs as well as donating to charities. His main spending issue is on food as he eats a lot to maintain his big frame.
Giles' ambition is to bring justice to those deserving and to free those wrongfully imprisoned. He enacts his twisted sense of justice by murdering and slaughtering human traffickers, corrupt people in positions of power, and people akin to those previously listed. He would go the extra mile and then some more to achieve his goals and to complete his jobs. To him these contracts are simply another means to his ends. In his world his actions are justified and would he ever come to break his own moral code he wouldn't know what to do with himself. He is willing to sacrifice his life if it means the world will be better and clean of vile people. His end goal is justice for all.
Giles' most defining event and set him on his path of twisted vengeance happened when he was younger. His family was indicted, persecuted, and charged with illegal occult practices wrongfully. Due to this charge his family was sentenced to pressings, as a result of said pressings his family were murdered under all the weight while he remains the only survivor his face is disfigured from the weight. Ever since then he wears a voors head device to hide his disfigurement and as a means to protect his identity while he works although the general public knows who he is while the underground world simply knows him as "Pondus Lustitiae" or "The Weight of Justice"
