[[quotebloc]]Child of a god whose domains are luck, storytelling, charisma, and writing? And how might two siblings bouncing around the foster care system subconciously use those gifts?[[/quoteblock]]
Super luck might be a big help in dealing with foster care. They 'just happen' to get randomly placed with a good long-term foster home, and random chance keeps sending them back there after switching homes. Plus, random chance keeps them meeting up with foster siblings they liked, or with classmates they liked who just happened to change schools to end up in their new school. They get a sense that anyone they didn't like they'll never see again and anyone they liked they'll run into eventually, which makes them less fearful of forming bonds with people.
If I'm asking for advice on a story idea, don't tell me it can't be done.
