Mine was a Wild Magic Sorcerer that vehemently believed he was a regular city guardsman and explained every bit of magic he produced away as pure happenstance.
Shadowrun 4e. A hacker who was way into drag racing. I got really into statting his race car, and even made driving equal to hacking. He was in deep in the underworld, trying to buy his childhood friend out of her indentured servitude at a brothel.
Mad Max style wasteland campaign: A Shepard boy, skilled at archery, wandering the wasteland with a talking dog (who was named Blood, but wasn’t evil). I saw this kid as being on the more idealistic and good side, and I picked a concept connected to society in contrast to what the other PCs picked (A reformed Mohawker, a powerful mutated woman wielding a stop sign, and a “priest of KISS” following the concert routes his roadie parents took before the bombs dropped, mistaking them for religious pilgrimage)… sorry that one had a lot of gas.
Superheroes: A jewish journalist who learns he is the inheritor of the Golem of Prague, and with it, a tradition of Talmudic magic. The other party members were a Bisexual paramedic/ vigilante by night (me and her player agreed that we were roommates lol) and the last one was a black teenager who killed a cop after he had paralyzed his brother. The campaign started and we were “the cop killers” and were protecting a small minority community but I keep thinking that had so much gas in the tank and room to grow and I might spin that off into its own campaign.
I’m just so sick of heroic high fantasy
I’ll preface this by noting that the sin of sloth has traditionally been understood to be a sin of omission, not just commission, i.e., you are insufficiently devoted to the things you ought to be.
Which means you could, in theory, have a (reflavored tiefling) devil paladin so devoted to sloth he works against evil causes. He’s not interested in good per se, it’s just that advancing the interests of good and traveling with a good adventuring party has the best ROI for failing to carry out his evil responsibilities.
Naturally, this has caused a fair amount of controversy among sloth devils, and there is a multi-century trial going on in the Hells about whether this ought to be allowed. This is not expected to be resolved in the foreseeable future because the advocates for both parties keep filing their responses well after petition deadlines expire.
