“Valhalla, may I speak to you please?”
 
“Of course, Princess.” Val followed her teacher into the stained glass hall, before guards closed the door behind her. “Is something wrong?”
 
“Not at all. For me, at least.” Celestia sighed heavily. “My sister’s magic is growing weak. Just as mine once did. Look at this scroll.”
 
Val took the parchment, reading it aloud: “Sister, I may not have much time until my lunar magic is completely powerless. You must find someone who can carry in my hoofsteps, as Valhalla did for you…. Wow. But how are you supposed to find someone if you have to stay here and rule Equestria?”
 
“I don’t need to. This is a job for you.”
 
 
Don’t worry, Luna’s fine. In this universe, when the princesses’ magic starts fading, they need to find someone to carry on their power. Celestia found Valhalla.
