I'm currently writing a Pixie Hollow x Homestuck cross over where they're all Fairies lol. I didn't include the other fairies from the actual movies, but I did think a long time about what kind of fairies each character would be. I made Rose a Light fairy but she uses sunlight from old seaglass and pixie dust to foretell the future. And Kanaya is a Tinkerfairy who is a tailor for clothes during the day, and a Historian by night who knows all about the sordid history of Pixie hollow.

Rose likes Kanaya, but Kanaya finds Rose to be too stuck up and is a bit jealous because everyone seems to want magical fortunes instead of coming to her to learn about the practical truth of the world lol (Like Magic vs Reality :3) But they make up in the end so its all good (when I get to that chapter anyways)
