Celestia looked at Philomeena, her pet phoenix, suddenly reminded of a...certain pony she had to contact.

She sighed, remembering how closely this certain pony had watched Gylden Glør, thousands upon thousands of years ago...

Fugl Føniks...I need you...

Her horn glowed, and she melded the words into a spell, calling forth one of the only living Elders, the Language of the Elders calling him forth...

The pony appeared in a blast of fire, born anew, just like his namesake, his name echoing as Celestia uttered the words.

"Fugl Føniks, do you understand why I have summoned you?"

The pony stretched his white wings, and sent an experimental burst of energy through his horn, his blood red hooves in stark contrast to his white body, a black band separating the red cloven, a likewise pattern seen in his sword-like hair.

"Yes, My Princess. And not only I, but Mørk Blusse and Hvit Brann do as well."

Celestia nodded, remembering the two personalities that the pony could call upon, and even meld.

"Well, I believe we should call you by your Equestrian name for now."

"Would it not be better if I keep my Ancient name, the name of power, through which the world functions?"

Celestia shook her head, her gaseous mane trailing behind her.

"For what you must do, Fugl Føniks, it is best that you adopt your Equestrian name."

"Tell me, O Righteous Princess of the Sun, what is my Equestrian name?"

"You need only look behind you, and you shall find your namesake."

Fugl Føniks turned around, and came face to face with Philomeena, the phoenix priming itself, its feathers of flame glowing with a vibrant life.

"...My Equestrian name is...Phoenix?"

Celestia nodded, her gaseous mane whispering, its secrets forever hidden.

"Yes. And you, Phoenix...as one of the only surviving Elders, you must watch over the Six Elements of Harmony, Spike, and Peter Roose."

Phoenix nodded, his sword-like hair whispering in consent.

"I remember when he arrived. The other Elders urged for action. However, Hvit Brann and I disagreed."

"Ah, and your personalities...you must know their Equestrian names. They are Dark Haze, and White Fire."

Phoenix looked straight at Celestia, his eyes suddenly burning with a fire, the embers white and interested, emulating the fireball cutie mark on the alicorns' flank.

"I see that you forgot about Gylden Glør, Princess. Why's that? Are you so old that you're having lapses in your memory already?"

Celestia rolled her eyes, remembering the personality that now controlled Phoenix all too well.

"No. He was not an Elder. When he died, he gave up everything. Luna and I forgot all about him, and the only pony in the world who remembered him was the Dreamer. Now, Phoenix, if you would not mind, please, remove either your wings, your horn, or both."

"W...what?"

"You heard me. In this day and age, there are only two alicorns. It would cause chaos in my realm if a third rose."

"I'll disband myself of the horn, then. The wings, I shall keep."

"Good. Now, if I may continue undisturbed, White Fire..."

"I'll keep them both down, Princess..."

"Thank you. Now, I need you to follow the train the eight of them are on, and ensure that their minds, bodies, and souls remain unharmed by Discord."

"Ah, Discord...unfortunately, Metall Kant kept me abiding to the 'Laws' of the Elders. I couldn't go down there and bust up his statue..."

"Phoenix, you need to practice keeping your personalities down. You haven't been a pony for about ten thousand years now, and Dark Haze is too rash for this. You must re-learn how to control your personalities."

"Yes, my Princess..."

"Good. Now, go, Phoenix, and protect the Elements of Harmony, Spike, and Peter Roose with all of your might. If needs must, I permit you to meld Dark Haze and White Fire."

"Thank you, my Princess..."

"And one more thing before you go."

Phoenix rolled his shoulders, putting his wings down, even as his horn fully disappeared, magical core and all.

"Yes, my Princess?"

"I congratulate you on watching the culture of Equestria so closely, as you have not been using the Royal Canterlot Voice."

"Well, I kind of had to. Comes with the job of being an ancient being presiding over all of Equestria. I kind of have to follow the times."

Celestia rolled her eyes.

"Just go, White Fire."

"Y-Yes, my Princess."

Phoenix walked over to the window, preparing himself, when Celestia whispered something into his ear. He blinked, surprised, but nodded nonetheless.

He took off, his horn finally fully gone, his cutie mark hot with excited energy, his wings flapping faster and faster, getting used to his old body, ready to take on anypony, and anything, that stood in his way.

I will not let Discord win this one...never shall that evil, disgusting being ever taint this world once more...

I've introduced one OC, and I'm still accepting new ones.
So, if you have one you want to see in this story, just give a short description below.
Oh, and the pony's name. Duh.
I'll try to include all ponies.
And, even if it seems as though it's really thick with OC's, send one in, and I'll just fit him/her into a new setting. However, there are certain points when I'll have to reject certain OC's, and if it comes to that, I apologize sincerely. But, like I said, I will try to include all ponies.
Ahem...
INCLUDE ALL THE CUSTOM PONIES!
