Calcifer.

"What do you mean Zacora left?"  Rainbow Dash exclaimed.

"I mean that she left the Everfree forest!  When I went to see her I found this note on the door."  Twilight quickly nudged her saddle bag and retrieved a parchment of paper.  Being hasty, Rainbow snatched the note out of the purple mare's mouth, "Let me see that!"

Rainbow Dash decided to read the letter out loud, that that the other ponies could hear.

To whom it may concern, this is my farewell letter.

I'm leaving on behalf of... certain reasons.

"Wait... she's not rhyming."  Rainbow eluded.

""KEEP READING RAINBOW DASH!" Pinkie yelled.

Although it fills sorrow in my heart that this is the way I say goodbye to my dear friends of Ponyville,  I ask that I be remembered.

I'm returning to my homeland if anypony wishes to know my whereabouts.

Do not try and find me, for I in no way wish to return.

"Why did she leave?"  Fluttershy murmured.

"There's more."

This letter is not only a goodbye letter, but a warning to everypony in Ponyville.

"What?" Lemon asked.

Rainbow Dash ignored him.

Over the last seven days I've been in Everfree.  I've been witness to... strange occurrences.

"Strange occurrences?  Stranger than what's already in those ghastly woods?  Oh my..." Rarity out spoke.

"WILL YOU GUYS SHUT UP SO I CAN READ!"  Rainbow remarked.

"Rainbow, we're all in shock at this.  Just keep read'n and we'll keep list'n." Apple Jack soothed.

"Fine!" The cyan Pegasus retorted.

I've witnessed things that I fear my safety for.  Blue fire. Singing.  A Hooman...

"Wait... A what!?"  Twilight interrupted.

"Uh... a Hooman.  What is that anyways?"

"I... I don't know.... Keep reading, I'll go see if I can find something on it."

Twilight trotted to her upstairs loft, where she kept her book on zoology and myth.

Rainbow kept reading to the other six.

According to my kin, a Hooman is something of legend.

"Twilight be sure to look into legends!"  Rainbow yelled upstairs.

"Got it.  Still looking."

A Hooman is said to be a great creator, but also a great destroyer.  They are said to be about up to six feet or less in stature, and can speak many types of languages unknown to our kind, or any kind on Equestria.

"That sounds scary..."  Fluttershy winced at the thought.  The six, including Spike were deeply engrossed in what Rainbow was reading.

Not known is much of the Hoomans.  They shouldn't even exist.  They are of a story the Chief of my tribe made up for the enjoyment of our young.

"Oh..."  Twilight said from upstairs, finding out that her search was for nothing.  She trotted down the stairs while Rainbow kept reading.

Whatever this beast in Everfree is, it matches the description of the Hooman.

Please, I beg of you citizens of Ponyville.

Stay out of Everfree.

That especially means you and your friends, Twilight Sparkle.

Twilight blushed a little as she joined her six friends and dragon,  they just looked at her with expectant smirks, somewhat amused at the sentence.  They all turned back to Rainbow Dash.

"Is there more?" Spike asked.

"A little."  Rainbow answered.

Hoomans aren't said to wield the power of fire.  This is the only difference in this beast.  (If it is a Hooman.)

I must go now.

Farewell Ponyville... I shall miss you sorely.  You've been warned.

-Zacora-

Lemon Squeeze, Twilight Sparkle, Pinkie Pie, Fluttershy, Apple jack, Spike, Rarity, and Rainbow Dash all went silent.

...

"I'm Confused."  Pinkie finally said.

"What in Equestria is going on here?"  Apple Jack asked.

"Apparently..."  Twilight remarked, "Colgate was right."

"Well, what are we going to do?"  Lemons asked.

"If we tell Ponyville this, they might panic." Apple Jack said.

"You might be right A.J." Rainbow spoke.

"Twilight, what should we do?"  Spike questioned.

Everypony in the room stared at the purple mare.  Twilight studied the situation.  Ponyville might do exactly what Apple Jack said, Panic.  If Everypony does panic, it surly might bring out the monster.

Which wouldn't be good, especially if it can control fire.

Twilight brain-racked for about a minute on the subject.

"Well?"  Rarity inquired.

"I... I don't knOH!!"

"What? Whats wrong Twi?" Fluttershy asked.

"We need to tell Princess Celestia, she'll know what to do."

Twilight galloped to the desk with the statue of the famous "King Knight's head" as the centerpiece, and pulled out some parchment with an ink container and a quill.  She started writing.

"Twilight, you shore the Princess would be of any help in this situation?" Lemons asked.  He made his way towards her, along with the other six.

"Of course Lemons, Princess Celestia has been here for over a thousand years.  I'm shore she might know what this "Thing" Is."

Lemon Squeeze looked quizzical, but his only question had been answered anyways.

"So, you do believe that the monster exists?"  Fluttershy questioned.

Twilight stopped the motion of her quill, looked up to Fluttershy and said, "Yes."
