Tantabus, such a similar name.
Ah...sometimes, i just LOVE how even my dear Lulu with all those centuries on her back, can be such a fool, thinking to simply control a nightmare as it was nothing more than a simple animal.
I believe that i should introduce myself.
I have been called many names during the centuries.
Dark-Pony, Bad dream, Night terror, Incubo, and more recently Nightmare.
I'm Tantibus, the only TRUE source of all nightmares, fears and phobias.
I believe you already spotted the dimilarity in the name.
Tantabus-Tantibus, ah....i do thank Luna hovewever for allowing he to feed upon her fears dor so much, enough to allow me to permanently take back my place in the Dreamworld.
But..i'm misleading you aren't I? Allow me to start from the beginning.
I exist since the very beginning, before the two Demigod Princesses, the Chaos God and of course any other creature.
At first i was just a little, barely sentient droo of darkness in the ethereal planes of existence, a "mistake" as Creator called it.
Of course,even in that miserable stage, my power was great, enough to cause the first Ponies to perceive me, and soon, finding in me the source of most of the phobias that plagued the ponykind.
Funny how their own racism towards the other races only fueled me, the Unicorns were the eheh "nightmare" of the other ponies since they could rise and lower the sun.
When Equestria was founded, the things started to turn against me, their major experts id Occultism were decided to eradicate me, snd they were near it.
Then, He came.
Oh what glorious feast it was, with the Gid of Chaos torturing all the three races i was just TITANIC, when they thought that rest would have gave them peace, i appeared torturing them in even worse ways, sometimes particoularly delicacies couldn't even wake up anymore, they had their very soul eaten or shredded to bits.
I believe...this was when things went overboard, Creator sent it's daughters, two Demigods with the natural and innate power to control the two celestial bodies.
They imprisoned the God of Chaos and with their reign completely cut my fuel...i had returned just a tiny drop of darkness within the Dreamworld.
I don't know how much time passed before an expert Occultist, the strongest i've seen in ages, managed to forcefully summon me within the material plane, his name was Sombra, and to my surprise, it was just a colt.
The moment i saw him, i knew this was exactly what i needed, he wanted power, i needed sustainance.
With me by his side, he became the most powerful unicorn in Equestria, second only to the Princesses's councilor Starswirl.
Hovewever,once again my glorious projects were stopped as the two Diarchs used a newfound power to sigil my pupil into the cold ice, he brought the entire city with him.
Once more, i was a barely sentient worm in sn ocean of dreams, this time though, i gad true fear that it was my doom, as one of the two Demigods, named herself Guardian of Dreams, completely destroying my few feeding attempts.
I was barely clinging to life, when every fiber of my spirit trilled as i felt an emotion wjicg taste i gad long forgot.
Hate, hate of the purest one, harsh and violent coupled with an overflowing amount of jealously and sorrow.
You can imagine my surprise when i found which of the sea of doors was pouring such emotions.
Once more, the emotion was so pure, so true that i was able to briefly manifest on yhe material plane.
Ah Lulu...ehat a beautiful moment that was.
She alone crying desperate and in a rash greedily accepting my offer to help her.
Her Soul was just...umbeliebably good, i wouldn't dare to touch such perfect work of Creator.
We agreed to mutually help.
I would have gave her the strenght to overcome the Sun, and she would have allowed me to access every dream of everypony, but her precious Lunaris Clan and the Bat-Pony kin.
I miss those days, even when we were trapped on the moon, we persecuted others with Nightmares.
Hmhm.."Nightmare Moon" what a pretty name you had choose Lulu.
And now, after all this, you blame me, and hunt me down when you dirst asked my help.
Trust me on these words, whoever will read this.
Tantabus may have been defeated, but he was just a mere illusion.
I know Lina better than herself.
Soo. Or later, she will feel again discouraged and in need of help.
And i'll be there.
For her.
I'll always be there, no matter what anypony may do.
Luna needs me.
This is just a momentary set back, for the Nightmare as just begin.
Fin?
