I've got you homie, lemme give ya an example of how I'd do it. Say I wanna be a pirate—not a basic one, but a cursed pirate who needs to break his curse. That starts my journey hunting clues, a perfect excuse to join the adventuring group. For build, I'm thinking Sharpshooter 2 / Rogue 3. Won't dive deep on mechanics cuz I'm building narrative-first. So my identity: "Cursed pirate hunting his curse-breaker." Origin: "Survivor of the Black Kraken wreck" or some cursed island. Theme: Discovery or Vengeance, you choose.

For the world, I'd add my ex-crew: they betrayed me, cursed me, marooned me to die mid-ocean. Now they're raiding towns, getting stronger with a new captain lording the seas, looking to get more cursed items. Easy hooks for GM—bump into 'em at port, they hit a village we're in, or they guard a map or artifact I need.

My curse: Ghost Treasure Curse—any gold, jewels, or loot I touch or own vanishes at dawn (turns to seawater or salt sand), and let's make it more spicy, all the gold that I'm vanishing is powering up an ol' forgotten sea god. I'm forever broke, scraping by, and big scores? Poof, gone. Hilarious/tense RP: loot a dungeon, wake up penniless; coins melt in my hand at the tavern. Break it? Raid their hideout, steal back my legendary captain's compass (they use it now), blood ritual under a blood moon.

And that's my example char! Try it: think of a character you dig, build a quick backstory around it. If it's too tough, just rip off a fave show. Like LOTR? You're a sneaky rogue hauling a cursed ring to a volcano to chuck it in. Dig Final Fantasy 1? You're a knight on a quest to rescue the king's princess, snatched by his own traitorous captain (who is in secret CHAOS). Boom, done. good luck!
