when i decided that I actually wanted to write this story(It's going to be either a primarily character-driven comic or a children's novel series, still framing out the story), I put the characters aside and focused on the world's basics.
how the worlds of faeries and humans could be separate, where the spots they overlap would be, and how to reach them.
Then the basics of the plot. There's human who navigates? There's a ship full of lost faeries trapped in the human world trying to go home. The human has no reason to seek them out? Well, he's on the run. He hasn't located the Faerie-Human world overlaps bc he didn't really know this was a thing until now? Neither have they, that's why they're lost? Give them many adventures to go on, like Sinbad, but with more character growth.
