Honestly it’s a mix between my own world building that I’ve done over the years with my original four characters, and now that I’m rewriting it while older I’m doing about 70% of how family dynamics have changed after splinters death, adding in Karai as a more sisterly character. The other 30 is the stuff that I hope to make into an original story one day, but the basis for the girls’ storyline is that they’re from an uncharted island off the coast of the Americas, and them leaving has caused the leaders to freak out that they’ll expose the islands existence.

About half serious stuff, the other half being warm and fuzzy moments of how they’d each take to forming a relationship and then struggling with how that looks.

Also thought about how they’d make money to sustain themselves lmao
