Cozy Glow delivered the mail for Princess Twilight or Headmare Twilight in this case, she really didn't know what she should call her. She got the mail from Derpy, and helped a bunch of students with their problems along the way to the office.

"The mail's here already? What time is it?! I'm late for my class's field trip to Cloudsdale!" Twilight began panting.

Cozy Glow then calmed Twilight down and began speaking to her calmly "Don't worry. I asked Professor Rainbow Dash to cover for you."

"And she said yes?" Twilight asked in a questioning tone.

"Uh-huh. I told her how busy you are and how much her loyalty meant to you. I also color-coded your teaching schedule by friendship element and cataloged all the magical artifacts in the school. I hope that's okay." Cozy Glow explained before getting a bit nervous as she didn't know if she was supposed to do that or not.

"Okay, Cozy Glow that's fantastic you're like my right hoof pony." Twilight said happily.

"It's like you taught me. Helping is what friendship's all about." Cozy Glow explained happily flying around the office.

"Exactly. And hopefully my class is learning that on their field trip right now." Twilight said in confirmation.

"I heard they might do some sightseeing first." Cozy Glow said.

Meanwhile, In Cloudsdale

"Ta-da ! The Pegasus Weather Factory!" Rainbow Dash said "Every drop of rain or flake of snow comes from there."

The students awed.

"I know, right? " Rainbow said " Hey ! The cool stuff's over here!"

"Wow ! I've never stood on a cloud before . " Ocellus exclaimed .

" You can't normally. But for our trip I cast a spell that lets us walk like pegasi " Starlight explianed walking on the cloud.

"Hey Yona ! Come check out this view !" Gallus said " Unless you're too scared."

"Yona not scared. " Yona said . All of a sudden Yona fell through the cloud.

"Now Yona scared!"

The others looked shocked but then the other non flying creatures fell through the clouds .

"Come on" Rainbow Dash said "We gotta catch 'em "
Starlight and The creatures falling screamed but they all got caught. Yona started screaming but she got caught by Ocellus and Gallus .

"Gotcha ! " Gallus said .

" It's okay, Yona." Ocellus said "You like flying ,remember?"

"Flying, not falling " Yona replies as Ocellus and Gallus put her on the ground with a "thud". Yona starts kissing the floor .

" I don't understand " Starlight said "It's like my spell stopped working. That's … never happened before."

After a while the door opened with Rainbow Dash and Starlight rushing in.

"We have an emergency." Starlight said worried.

"The students dropped out of the sky." Rainbow Dash said scared.

Cozy Glow's eyes then widened. "What are they all okay? She asked very worried about her friends.

"Slow down tell me exactly what happened." Twilight said calmly.

"I cast a spell for our field trip to Cloudsdale, but my magic just failed." Starlight explained.

Rainbow Dash backing Starlight up then said "We barely caught everypony in time!"

Twilight then embraced Starlight making the latter blush, Cozy Glow watched this raising an eyebrow.

"I'm glad you're all okay, but I'm sure it's nothing to worry about, Starlight. Maybe you did your spell wrong. Let's take a look." Twilight said happily making Starlight frown annoyed while Cozy Glow got suspicious Starlight never does her spells wrong.

Twilight tries to take a book from a shelf but it drops to the ground .

"I didn't drop that book." Twilight said .

"Maybe you did your spell wrong." Starlight said sarcastically, obviously bothered by Twilight's comment from earlier .

Now Cozy Glow was worried this cannot be a coincidence.

Then they hear a thud from outside .

"Ow!" Rarity exclaimed .

The door opens and Fluttershy and Rarity come in.

" Rarity ran into the door " Fluttershy said .

"My magic is go-o-one ! " Rarity said , sobbing " I even had to use my hooves to coil my tail!"

" Still think there's nothing to worry about ? " Rainbow Dash asked Twilight.

"That that doesn't make any sense" Twilight said "Magic can't just disappear . Something has to be causing this."

" Um ,didn't we learn in class about a creature that eats magic ? Ter,Tee….Tir- something ? " Cozy Glow said .

Fluttershy gasped "Tirek!"

Spike then came inside choking, Cozy Glow was worried so she grabbed on to the small dragon and used the heimlich mannuver getting the letter out of his mouth.

"Thanks I never got a letter stuck there before." Spike thanked Cozy Glow.

"It's from Princess Celestia we've all been gathered to an emergency meeting at Canterlot, look." Spike explained holding out the letter.

Twilight tries to levitate the scroll but her spell fails.

"I'm pretty sure I know what it is about." Twilight said .

Later, In Canterlot.

"Throughout our city, ponies have been reporting tales of their magic failing." Princess Celestia said "Spells going wrong . Potions not working."

"Even raising the moon has become difficult. Are there similar troubles in Ponyville?" Princess Luna asked Twilight .

"Yes . We experienced it first hoof." Twilight replied.

"It's the same in my kingdom." Princess Cadance said "The Crystal Heart seems safe for now, but I worry if this continues."

Then the door opened and a mail pony came in with a letter.

"Letter for the princess from Star Swirl the Bearded!" The mail pony said .

"Gasp! It is even more terrible than we feared!" Princess Celestia exclaimed "Magic is disappearing all across Equestria!"

The ponies gasped.

"Star Swirl believes the power will drain from our land in three days." Princess Celestia said reading the letter "First , unicorn magic and spells will fail."

"That's what's happening now!" Starlight exclaimed.

"On the second day,creatures will lose their magical abilities." Princess Celestia continued .

Fluttershy gasped. "Oh no!"

"But why is this happening now?" Princess Cadance asked scared.

"That's the worst part." Princess Luna said "We have no idea."

"Has anypony checked on Tirek?" Twilight asked.

"You mean the big, red, scary centaur who eats magic?" Pinkie Pie asked her "Why would we wa— Ohhhh . Riiiiight."

"If he has found some way to escape his prison or work from within it, he could be responsible for this." Princess Celestia said putting a hoof on her chin.

"That is the best explanation so far." Princess Luna said " Somepony should investigate "

"We'll go." Twilight said happily.

"Oh, no-no-no-no-no-no." Rarity said "Not without us , you wo— Wait . Did you say "we"?"

"I've finally learned that it's okay to count on your friends for help." Twilight explained "Um, you do want to come, right?"

"Uh, duh!" Rainbow Dash exclaimed flying up to Twilight.

"Thank you all." Princess Celestia said "We will search for ways to protect Equestria in your absence."

"Be careful . Tartarus has changed since you were there." Princess Luna said "It now holds many dangerous creatures, and you won't be able to rely on your magic."

" With her friends by her side , she won't have to." Applejack said as she and the rest of the Mane 6 embraced Twilight.
