Everyone knows that two mares can't have a foal. . . unless their best friend is one of the greatest magical minds in Equestria.
Applejack and Rainbow Dash went to Twilight Sparkle with a simple question: Could she make a spell that would allow them to have a foal together? After a year of magical research, Twilight thinks that she's done just that. But the spell is not without potential side effects, and AJ and Dash have to decide if they're ready to be part of a magical experiment that could give them a foal of their own, or cost Applejack her life.
