Celestia and Luna arrived at the library. They quickly entered and barricaded the door. The princesses quickly began to search for the book they needed.
“Got anything Luna?” Celestia asked.
“Nope, nothing.” she replied.
Few minutes of searching later, Celestia found the book she needed.
“I got it!” Celestia said in excitement.
“That’s great.” said Luna. “So what do we have to do?”
Celestia began to read the contents.
“Well that sounds simple enough.” said Luna.
“Mmhmm. It even works on non-ponies.”
The princesses headed out of the library to stop the apocalypse.
The princesses flew their way to Ponyville, finding their number one priority, Twilight and her gang, zombified and slowly approaching them.
“We’re gonna need more help to stop the apocalypse. These seven are our only source of help.” said Celestia. “Get ready with the potions sister!”
As Luna raised the potions with her horn, an unexpected attack from the zombified dragon, Spike, leaped at her.
“Aaaaaahhhhh!!” Luna shouted as she kicked the zombified dragon back to the six ponies.
Though Luna avoided the attack, it caused her to let go of the potions and dropped them. Glass shattered on the floor with pink liquid spewing out.
“Oh no! The potions!” Luna exclaimed. “What do we do now?!”
“We can’t take them out, we mustn't.” Celestia said. “They’re still the Elements of Harmony. They’re the ones who saved Equestria more times than I can remember. Taking them out wouldn’t be right.”
“We’ll just have to go back and make more potions.” Luna stated.
As the princesses flew back to make more potions, zombified pegasi surrounded them from all corners. The princesses were trapped. They couldn’t fly up nor down. They couldn’t fly forwards nor backwards. They were trapped.
