ONTO THE STORY:
"Once upon a time in a land called Equestria, there were two sisters who ruled together and created harmony for all the land.
To do this, the eldest would use her unicorn powers to raise the sun at dawn. The youngest brought out the moon to bring in the night. Thus, the two sisters maintained balance for their kingdom and their subjects-all different types of ponies. As time went on, the younger sister became resentful. The ponies relish and played all day when her sister brought warmth, but shunned and slept through the beautiful night.
One fateful day, the younger uniform refused to lower the moon in way for the dawn. The elder sister tried to reason with her, but the bitterness in the young one's heart had transformed her into a wicked mare of darkness named Nightmare Moon. She vowed that she would shroud the land into eternal night.
Reluctantly, the elder sister harnessed the most powerful magic known through Ponyville-the elements of harmony! Using the magic of the elements of harmony, she defeated her younger sister and banished her permanently to the moon.
The elder sister took responsibility for both sun and moon, and harmony has retained in Equestia since."

(Name) was walking down the road to her library, her book secured safely in a harness, when three unicorns stepped in front of her. "There you are (name)." One of them said. "Moon Dancer is having a little get together in the castle courtyard. Wanna come?" The three ponies stepped a little closer to her with excitement in their eyes. (Name) hesitated for a moment before answering, "Sorry girls, I got a lot of studying to do." She gave them a weak grin before dashing off to her study room. One of the unicorns sighed before asking her companions, "Doesn't that pony do ANYTHING besides studying?" She sneered before replying, "I think she's more into books than friends." Before trotting off the opposite direction of the geek.
