It was a Dark and Stormy Night...

well not exactly, It was mostly cloudy though, but enough about that. Princess Celestia and Luna were getting ready to preform their duties, which consisted of Luna lowering the Moon so Celestia could raise the Sun.

There was one problem though,

the Moon was still up.

Celestia, enraged rushed to Luna's room, asking her why she hasn't lowered the Moon.

"I'm trying." Luna replied."It's not working."

Celestia, in disbelief, attempted it herself.

Nothing.

In one last attempt, they both tried at once.

Still nothing.

"What has caused this?" Asked Celestia.

"I have no idea.", Replied Luna.

          ~~~*><*~~~

"HELOOOO, Ponies! Are you ready for a nighttime party?" Asked Ever-Joyful Pinkie Pie, as she rushed to Sugarcube Corner with a bag full of party supplies.

"Pinkie, it's the middle of the night, Ponies are trying to sleep." Said Twilight Sparkle, from her Library Balcony.

"Aww, wheres the fun in sleeping?" Asked Pinkie.

"Pinkie, d' ya EVA' sleep?" Asked Applejack.

"Sometimes, But i mostly Throw Parties!" Replied Pinkie.

"Ah' didn't jest' Meet ya yesterday."

"Ugh, I need my beauty sleep!" Shouted Rarity, donning a bathrobe and face mask.

"Pinkie, you've woke just about everypony up." Said Twilight.

"Fine, but if you need to talk to me, I'll be at Sugarcube Corner, decorating for the party!" And with that, Pinkie Pie dashed off.

And everypony followed.

After a series of Cupcakes, Pin the Tail on the Pony, and various other Pinkie Pie party shenanigans, Pinkie called the party off. "I hate to stop such a great party, but we DO need our rest." Said Pinkie.

Suddenly, Twilight rushed Back in.

"I don't mean to alarm anypony, but the Moon doesn't look like it's moved!" Said Twilight, alarmed.

"Yeah, yeah, Luna's probably slacking off." Said Rainbow Dash, as she flew back to her home in Cloudsdale.

"This is too urgent to blame ponies! Spike, take a letter, to the Princess."

As Spike got out a scroll and quill, Twilight started the letter.

"Dear Princess Celestia,

It has come to my attention that the moon has not moved in the past few hours, weather or not this is an accident, or Nightmare Moon has returned, is not clear, but still, we must take immediate-

"Wait- how do you spell immediate?" Asked Spike.

"I-M-M-E-D-I-A-T-E" Said Twilight.

And Spike scribbled it down.

...we must take immediate action,

                                  Signed- Your Faithful Student

                                              Twilight Sparkle"

"Now send It, this is urgent."

And Spike sent It.

Moments later, Spike belched out a new Letter.

And he read aloud.

"My Faithful Student Twilight,

I have noticed this, and we are doing what we can to solve this.

Your Mentor-

Princess Celstia"

"Hmm, this means even she doesn't know about it..."

     ~~~*><*~~~

As The Ponies were discussing how this could happen, a drop Of Black Sludge dripped out of the Everfree Forest, and started corrupting everything in It's path, No doubt, It was heading for Ponyville, FAST.
