(Draft for Solar Mare and Nightmare moon's first encounter:
"Power corrupts. Knowledge is power. Study hard. Be evil."
Solar Mare making imaginary circles with her golden armored hoofs on the ground started to talk.
tell me sister, what now? I assume there's a reason for waking me after so long."
"Well we could-"
"Let me guess" Solar Mare interrupted. "You want us to make a never ending day and night? A total eclipse if you may?"
The words where clearly taken from Nightmare Moon's mouth.
"Ha! Don't be so stupid. Your never ending night was nothing but a juvenile dream, a sad attempt of revenge, a desperate and pathetic cry for attention. All you wanted was to proof yourself worthy. Tell me, what exactly did you accomplished with an eternal night?"
" Nightmare Moon was caught with her guard down.
She was speechless; all she could do was shrug in her place, as if she wanted to disappear. How could her sister treat her like this? After all that time sealed away this is how she repays her?
what do you suggest we do?"
A grin crossed Solar Mare's face
-"I'm glad you asked"
Solar Mare walked towards the balcony of Celestia's room, Nightmare Moon following her. It was still night, the moon at the very top of the sky giving the castle and buildings around it a weak light almost as if it was a cloudy day.
-"Nightmare Moon, there is a reason why I was sealed away and not just banished." Solar Mare spoke with a proud attitude.
The beautiful purple night was all over Equestria. Celestia's balcony had an impressive sight of Canterlot, she could even see Ponyville not so far away. It was as if she could have an eye on her people all the time.
Equestria, such a marvelous land filled with so many magical creatures, everyone so different and unique and on top of them all, us. We stand as the dominant species, no matter how strong others can be, our magic and our minds will always prevail
And now it's ours. It is our Equestria sister and the both of us stand as the most powerful beings. We can rule together, we can make Equestria a better place for ponies. We can move forward
Solar Mare started to raise the sun
the pegasi were the first ponies on sight, clearing the clouds of the night so the sun could shine all over Canterlot.
A better place? Move forward? What do you mean?" Nightmare Moon asked confused
Tell me Nightmare. What's the difference between a pegasi and an earth pony?"
-"Well, that's obvious. The wings of course."
-"You are missing the important points
" Solar Mare replied angrily "the pegasi can fly, they can change and create weather. Every sunny day, every powerful storm, every sheer cold blizzard is made by them."
certainly true sister"
-"And now, tell me: What's the difference between unicorns and earth ponies?
-"Magic!" Nightmare Moon replied. "Magic that can be used to make life easier in every aspect!"
Solar Mare's expression changed to a cold face and her voice seemed to have changed to a more morbid tone.
-"You are starting to get the idea dearest sister."
The sisters returned indoors, making their way out of Celestia's quarters and started to walk down a large hallway.
-"Pegasi and Unicorns have special attributes that set them apart from the earth ponies
" Solar Mare continued as they walked.
but what exactly sets the earth ponies apart from the pegasi and unicorns?"
pretty much nothing"
Solar Mare stopped, this time there was no affection of any kind in her face, all trace of emotion disappeared in her eyes.
-"What do you mean by that?" Nightmare Moon couldn't say anything more, the confusion and awkwardness of the chat got to the top of her head.
Solar Mare and Nightmare Moon proceeded with their walk down the hallway. All the way to the end, giant golden doors carved with all kind of precious rocks stood, marking the limit with the private quarters and the public place of the castle.
-"The earth ponies offer nothing to our powerful nation. They can be seen as a pity worm in a perfect red apple, they are nothing but vermin to our species, a bump in our road to evolution! They are stopping us, we can't move forward because of them. Pegasi and Unicorns can make anything the earth ponies can 100% better and all, my dearest sister; it's all a matter of learning their ways."
Nightmare Moon was in shock
such an evil mastermind, a heartless and cold creature standing right before her, listening to every sound that came out of her mouth, analyzing every single word. It was clear. There was a reason for her sister to be sealed instead of just banished. Solar Mare was delusional, out of her mind and judgment. Power has blinded her, not only her eyes but in her mind.
And even so
the idea was perfect. She was talking sense. Earth ponies don't have, as cold as it sounds, a reason to live. They are holding progress for everypony in all over Equestria.
-"Dearest sister, don't get the wrong idea, but how exactly are we going to do that? Nopony will accept us as their rule-"
-"You fool!" Solar Mare interrupted.
"Look at us. We are GODS, we can do anything and anytime, and if anypony is smart enough to do the math, they will do as we say. Neither Celestia nor Luna are around, we are the most powerful beings in Equestria!"
" Nightmare Moon suddenly remembered.
"There's still five of the six elements of harmony, even if they can't work as they were intended, they have the magic and power to gather them again."
Solar Mare approached Nightmare Moon looking directly into her eyes.
"Sister...it seems you are forgetting something here. YOU have one of the elements of harmony under your control. With you and me it's impossible for them to gather them again."
you are right" Nightmare moon seemed to recover all her confidence
"WE are unstoppable. We can make Equestria a better place, we can mold and change its future as we see fit!"
-"Of course we can sister. Now let Equestria embrace her new Queens"
The two mares walked into the opening doors with all majesty, ready to impose themselves as the new rulers of Equestria.
