What happens when someone breaks their limit, what if they want to go even farther? In Rainbow's case, she went beyond anything she could even think to accomplish, but it will take time for her to understand. She has help but the actions she will take will decide more then just the safety of Equestria but the fate that bind their world to many. Rainbow will learn great things, important lessons, she is the first to enter this realm, but she will not be the last to explore.
