The Tale of Night Filly Moon

Months passed since she first opened her eyes. Days of dreadful heat passed, and more with freezing nights. Nights filled with strange sounds, and thunderous booms and howling winds. Days filled with dreary silence, and the occasional rainfall that dripped down in degraded stone and wood. Her hatred to this lonesome, unforgiving life then began. She yelled whenever her voice wasn't shot. She bawled whenever her eyes weren't dried out, and on those silent nights, she stared at the stars and had no sleep.

Eventually shadowy pony-shaped figures began to take form as the filly grew more and more insane. The creepy beings said no kind words, only whispers that fueled her hatred. Shortly after these apparitions appeared to her, whenever she'd walk past a reflective surface not covered in dust, she'd notice a glowing, dark blue smoke that would seem to emit from around her eyes, and every so often, would grin at herself.

It wouldn't take much longer before these beings would start doing her bidding. They would hunt, clean, even frighten away unwelcome visitors. They played music for her, no matter how depressing it was. The words they whispered shortly changed to that of temptation, "Take them. Kill them all. You're the spawn of terror." and the like. Their mouths never moved, not even a little, but the sounds still echoed around the castle.

Her anger continued to grow, and much like any filly, she'd have her tempers. She would go out into the forest and destroy trees, stomped on flowers, and every so often, creep on unsuspecting ponies, and watch from the shadows. Whenever one would get close to her, obviously suspicious, she would give a loud hiss, before disappearing back within the woods, and it wasn't rare that she'd return to the castle battered and bruised with no one yet to aid her wounds. Whenever she'd see out in the day how a foal might hurt themselves playing with others and they'd be tended to almost immediately and this, to the filly of no parent, was something that filled her hatred the most... But she remained silent.

So from this point, she started to search new ways of using her magic. She began reading through books of spells, even scrolls and ancient tablets. She furthered her learning in the history of Equestria and learnt of the battles won, and those that were lost. All the powerful enemies that previously threatened the kingdom. She fell almost in love with the myths and legends, and ideas popped into her head of how easily she could twist and bend them to however she desired.

One day, as she was searching in the bedrooms of the sisters, she found an unfamiliar trap door that wasn't yet put on the map for such things, and triggered it. Then some bricks in the wall then parted, and a faint blue glow came from inside. When she investigated more closely and entered the small chamber, she found the cause of such a glow. It was a thick, hard cover book, with Princess Luna's mark on the cover. She opened it, and spent days reading its contents. Examining each spell that the author had written down. Each night, she practiced such spells, and found herself dreaming. Many nights would be different, others mixtures of different things. She'd notice a pattern within each of her dreams. They included her loneliness, and her hatred to pony-kind. Most ended in sadness and disaster.

Further reading through the book of spells, she began practicing other spells, including entering other dreams and altering such dreams, as well as connecting them to others, despite the caution of such spells being magic hungry. Within the few months she was practicing, she had devised a plan to take over the ones she's learned so much about. The filly, although non-aging, grew with constant wisdom and intelligence.

As she studied the powerful book, she had also gotten to examining maps that had been collected up until the rise of Nightmare Moon. She circled specific locations as to where she would first attack. Her imagination ran wild as to what she could do to such a kingdom, and planned to let loose every ounce of it upon them.

"T-t-t-ta..." She began spouting out sounds, trying to speak the words she read. "T-Trussstt... M... Me..." she eventually grew more fluently, and continued with this method, practicing until she knew she had gotten it to something one might find influential. Her mind had become filled at this point, with vast knowledge. She knew most of the history of how Equestria came about, and how its past enemies had been defeated. She knew most of the areas Equestria controlled, and most importantly. She knew of their legends.

When she knew all that she could of the spells that were possible for her, she closed the book, and left the chamber for the last time, closing its entrance. She left the castle and took her next step in taking over.
