Somewhere in the Everfree Forest, a colt was picking apples and placing them into a basket. He picked the last apple and was about to place it within his basket, when he suddenly felt a very dark and ill presence. He carefully watched his surroundings and moved around. Then he cast an X-Ray vision spell to look for any signs of the danger, but to no avail. Then he cast a compass that lead him to the dark and ill presence. It pointed a ways towards the opposite mountain of Canterlot's.

The colt followed.

27 Miles Later...

The colt had been traveling for 2 miles, and to his surprise and suspicion, he never encountered a single dangerous creature... Well, there was a pack of Timberwolves, but they seemed to be running in a fright. Once his horn started blinking, the colt looked ahead and saw a cave, and that is where he felt the dark and ill presence. He teleported himself and the apples away.

2:00 pm - Canterlot Castle - Throne Room...

It was quite a peaceful day in Canterlot for the two Sisters. They sat on their thrones very quietly as the day went on.

"Today seems very well deserved, dear sister," Luna says to her older sister.

"Indeed Luna, it's not every day that a peaceful day is earned for Equestria," Says Celestia to her younger sister.

Luna simply nodded with a returning smile, "If I daresay, there could possibly be nothing that would ruin this lovely afternoon..."

But we all know the old scene that happens when one often says that, right?

The same colt with the baskets appeared in the Throne Room.

The colt had a green coat with an orange mane and tail, his eyes were pure sapphire, his horn was a little larger than Twilight's, he had long white beard, and his cutie mark was an emerald swirling above 3 small amethyst stars, and two streams of orange and white. Over himself he wore a deep ocean-blue cloak.

The princesses looked at the colt in suspicion and rose up, flaring their wings in grace. The colt looked up at the princesses and removed the hood. The princesses gave warm smile and folded their wings in, sitting back on their thrones.

"Emerald Shine, it is a great pleasure to see you," Said Celestia warmly.

"As it is to see the both of you, princesses," The colt known as Emerald Shine said, "But I do not believe that this is the time for salutations. There seems to be a very strong magic at work in a cave at the borders of Rambling Rock Ridge." His voice was strong but soft.

"What situation does thou speak of, Emerald Shine?" Asks Luna.

"There appears to be some kind of... infectious magic, your majesties," Emerald Shine said, unsure of how to make out what he felt from a cave.

The princesses grew worried about this. "Infectious, you said?" Asked Celestia.

"Indeed," Shine answered affirmatively. The princesses looked at each concerned about this 'infectious' magic. Luna turned to Shine to say something, but then a guard came rushing in.

"Princess! Stampede, from the Everfree Forest, the monsters are coming from the Everfree Forest!"

The princesses and Emerald Shine all had shocked and dreadful faces. The princesses immediately flared their wings and took of while Emerald Shine teleported away.

3:37pm - Ponyville...

The ponies all saw Parasprites flying out of the forest, worried that they might try to eat everything again.

"Don't worry, everypony! Pinkie is on the job!" Pinkie said with the instruments required for the Parasprites. However, when she was about to start, a parasprite came up to her and waved its front legs in panic. It started chirping and buzzing in fright. "What?"

Just then Fluttershy, Fluttershy walked up to Pinkie Pie. "What's going on?" She asked nervously about the parasprites.

"I don't know. I was just about to send them back to the Everfree Forest, but then this little guy just came up to me and started chirping and buzzing in panic," Pinkie said as she extended a hoof at the parasprite. "See?"

The parasprite was still buzzing and chirping. "Um... E-Excuse me?" She asked the little insect. The parasprite looked at Fluttershy. "C-Can you tell me what you and your friends are doing?" She asked. The parasprite started chirping and buzzing in a panic."Uh huh... Yes... Yes... (Gasp!) Oh dear! I don't know what this monster is, but he sounds awful!"

The parasprite simply nodded with a frightened face, and then it flew off with the rest of its hive.

"What did they say?" Asked Pinkie Pie.

"He said that 'it's' starting to wake up," Fluttershy answered.

Then, the rest of the girls walked by.

"It? Now what in Equestria would 'it' be?" Asked Rarity.

"What the heck is going on? The Parasprites are swarming past Cloudsdale!" Said Rainbow Dash.

"One of the little guys said that they're all relocating far away from the Everfree Forest," Said Fluttershy.

"Oh, well that's good ta know," Said Applejack.

"Actually, the Parasprites have lived in the Everfree Forest their whole life," Stated Fluttershy.

"How did ya know that?" Asked Applejack.

"Twilight gave me a book about all the monsters in Equestria," Fluttershy answered.

"Then why would they just suddenly move far away from the Everfree Forest?" Asked Rainbow Dash. Suddenly there was rumbling coming from up ahead. The girls and everypony in the village turned their heads to see that a dozen Prides of Manticores, Cragadiles, Cockatrices, Timberwolves, and other various Everfree Creatures running.

The girls gasp. "STAMPEEEEEDE!!!" Pinkie Pie screams. Everypony starts panicking and retreats inside the buildings.

The stampede of magical creatures were yowling, hissing, and squawking in panic, looks of anxiety and fear on their faces.

One of the foals looked at a manticore cub and two cockatrice chicks running and flying for their lives with their mothers and fathers.

"Mommy, why are the monsters scared?" The little foal asked.

"Don't look at the cockatrices, dear!" The mother said as she pulled her little foal back and closed the curtains.

As all of the creatures were running and flying for their lives, Twilight's friends were on the rooftops observing them flee. "Has anypony noticed that they're all afraid of something, too?" Fluttershy asked the girls.

"Ya know, now that ya- Get down!" Applejack and the girls quickly ducked as a cockatrice flashed by, squawking in anxiety and panic. They got back up and observed again. "Now that ya mention it, Fluttershy, they do seem to be afraid ah' somethin'," Applejack finished.

Then, the princesses and Emerald Shine landed on top of the roofs as well as they observed the creatures running and flying away.

"Hmm... So they are afraid of something..." Emerald whispered.

"What, Emerald Shine?" Luna asked.

"Earlier while I was investigating for the source of this infectious magic, I happened to have encountered Timberwolves, that seemed to running away from its direction," Emerald explained.

Celestia was observing the expressions on the creatures' faces, seeing that Emerald was correct. "Your assumptions are correct, Emerald Shine. These creatures do appear to be running from this infectious source you speak of," She said.

Then, all the ponies saw some dragons and hydras running towards the village as well.

"Dragons and Hydras!?" Pinkie Pie exclaimed.

"Alright, looks it's time to defend-" Rainbow Dash was cut off when the dragons flew over the village and the Hydras were maneuvering around the buildings in a hurry. "Our... home?"

"It would seem that even the largest creatures of the forest are afraid of this infectious source as well," Said Luna.

"Now, why on earth would those dragons and hydras be running like they were late for a family get together?" Asked Applejack. Then the girls looked over to see Fluttershy whimpering with her head under her forelegs.

"We p-probably d-don't want t-t-to know..."

"These creatures seem to be scared of this pestilential magic, probably even the source of it," Said Celestia.

"Perhaps it is best that we found out what it is," Says Emerald. The princesses agreed and they flew off to the direction of the infectious magic, Emerald Shine casting a flight spell and following. Twilight's friends saw them fly off and grew a little concerned. They decided to follow.

2 Hours Later...

The Princesses and Emerald looked below to see the Everfree coming clean of magical and dangerous creatures. They saw a dragon coming and dodged swiftly.

Twilight's friends below were seeing a lot of them just run around them. A pack of Timberwolves lept over them and kept running.

"It's like their all trying not to be late for an Everfree Festival or something," Said Rainbow Dash.

"This would be kinda cool if these creatures weren't almost stepping on us," Pinkie said. Then the girls looked ahead to see a certain Zebra heading the direction of the creatures.

"Zecora?" Applejack asked.

"Greetings my curious friends. It would seem that these creatures here are seeing that their lives here are meeting their ends," Zecora said in her usual rhyme speech.

"You're scared of whatever this thing is that's making all of these creatures run away from it, too?" Asked Fluttershy.

"The answer you all seek is why these creatures flee, and indeed what they know what is coming, even scares me," Zecora answered with a concerned expression.

"Wow, Ah've never seen Zecora like that before. I'm startin' to get the shivers mahself," Applejack said worriedly.

3 Hours Later...

The princesses and Emerald Shine looked below and saw that the creatures from the mountain were running from the source of the infectious magic.

"There!" Emerald Shine called out, pointing to the cave he saw earlier.

"Let's go," Said Celestia, the group flying towards it.

The girls below saw that the princesses and a unicorn by their side were flying towards a cave. "Come on, y'all!" Applejack said, and they all run for the cave.
