@Dutchess Sarah As the Haven only has normal classes until 18 years old, she could still train and live in the Haven with 20, but not attend to the "normal" classes. But yeah, she could also be an ex student that comes to train with the older guys and sometimes joins in the "special" classes. And she could also have this "high degree" power training with some other teachers. Like one on one and so.
