I don't know what to do with the rest of the Sunshadow series! My dad helped me come up with some ideas and you guys can help me decide! Here are what I have:
Maybe one receives the star power and it’s like the series that JLA already wrote
Maybe there is an astronomical event that explains why there are three black foals early
The fact that one is a filly might mean that she and one of the others mate and give birth to a “super-black” foal
The fact that there are three might mean that they each get slightly different powers, each with a weakness that has to be covered for by another/ the others
The fact that there are three might mean that there are three different crises that need to be resolved
....or something completely different! Please comment what you think should happen, with an explanation.
