(Takes place in AU during "To Where and Back Again, Part 2" for obvious reasons. Idea inspired by LittleshyFiM.)
When Thorax stops holding back and starts sharing love, magic is unleashed that causes not only the changelings to change but Starlight as well. In fact, the magic ends up changing her species completely.
To the shock of everyone, Starlight Glimmer is no longer a pony. Now, she is a changeling, and the queen of the changelings to boot.
Overwhelmed with this sudden change and the responsibilities that come with it, Starlight must quickly adapt and try to be a leader for her new hive. And this includes what to do with the former queen, Chrysalis.
