Appearance
Carter looks young. He can work with that. A few rough nights make him look older and a good nights sleep does the opposite. Makes it easier to skip around. He keeps his hair relatively short, same with the bit of facial hair he is happy to sport.
Fashion is just another way of blending so he doesn't care much about what he wears as long as ti gives the right message. Tank tops are his favorite but only so many places you can wear one without giving the wrong image.
His chest, back, and thighs are mostly tattoos. All of them done by arcanists and all of them doing different things, mostly quality of life. Keep away mosquitos, keep off a sunburn, help hold in power. If he were stronger he wouldn't need any of it.
His left arm has lots of small scars, shame really but he keeps needing the blood, the only scar that matters though is on his left ring finger. A thick scar just shy of an inch wide and going all the way around. His wedding band, cut in by his own hand.
Personality
Carter fully believes, lives, and breaths the phrase "Dirty deeds done dirt cheap." He is usually willing to provide a service and since his prices are competitive there is usually someone willing to pay. How many people are willing to kill someone down to the ghost?
Unfortunately Carter is also something of an asshole. He isn't heartless, but he certainly wishes he was. His family instilled some unsavory ideas into him on how people should behave. Took most his life to figure out his family might just be assholes too.
Most important thing to him, by necessity not choice, is his wife Darla. She's sweet, only a little homicidal, and the prettiest dead girl a guy could ask for. Marriage bound them, symbiotic relationship where she gives him power and he feeds her other ghosts. Simple enough. Not pleasant, not easy, but simple.
Dirty deeds, done dirt cheap.
Carter comes from a Family. Capital F. Got their start in New Orleans, plantation days, and since then has moved, hustled, stolen, and thrived in the muck all over the New World and a bit of the old. They've been around about 300 years, long enough and with enough kids to spread their name into lots of families.
Collectively they are called Les Cafards. The Cockroaches. Its insulting, and accurate. They tend to deal in the muck and despite a few tries their family never seems fully stamped out. Started with a plantation owner who learned his slaves knew some magic, the real kind. Wanted it for himself.
Did some bad stuff to get it.
But he didn't have the knack for it. His kids didn't either. Maybe they were jealous, maybe desperate, going theory is just greedy. Did some bad stuff to make up the difference in whatever it was that stopped them from really using magic the way they wanted.
But once they had a bit they wanted more. Lots of short cuts, lots of bad blood, lots and lots of worse choices. Skip ahead a few hundred years and we get James Carter.
As a kid his mom and dad got him ready for inherreting the family Rites. A grab bag of rituals, hoodoo, and what-have-you from the world over. And for his bride. That was how they did it in the end. Marry a ghost, bind her to the body, make her power you. No need for circles, save for the one you have to cut into your finger.
So Carter got magic, and it was everything his parents promised it would be. Assholes.
Carter cut and run from the family at 16. Nothing special, just the usual teen bullshit. He spent the next decade living in hotel rooms. Save for the two times he came home and almost got killed by his folks. Assholes.
Know what sucks worse? Getting told where you have to go next. Easthaven? Where the fuck is that? Well, wherever it is that's Carter's next go to. Since if he doesn't his bride made it very clear she would ask for a divorce in the most dramatic way possible.
