Currently, the universe contains Steven Universe, Gravity Falls, Miraculous Ladybug, Undertale, and some AU!Hamilton. There are influences (ex. characters being able to Apparate, though Harry Potter isn't one of the listed fandoms) from Harry Potter and We Bare Bears.
Everyone from the musical, I guess.
Characters can Apparate, use Floo powder, and other forms of transporation from the Harry Potter series.
