A/N: So the last chapters tensing was all messed up, but I'll live with it. This chapter takes place shortly after the events of the memories of last chapter, but I'll be doing it in simple past tense instead of the Frankenstein's monster I made last time. So, here we go with:
Chapter 2: Solitude
Luna, for what had to be the thousandth time in a little over two hours, turned her gaze towards the world, sighing in longing. She'd been foalish, she knew. Who was she to challenge her sister? She was just lucky that Tia had seen fit to banish her instead of killing her outright.
A creeping feeling was entering her heart, and she began to entertain the notions that she herself was at fault in this. She shook her head, trying to dislodge such thoughts. She'd been corrupted, there was nothing she could have done about it. Except maybe not have agreed to meet with that monster, she said to herself.
Quietly, Luna turned her back on her home, and instead decided to explore her new domain. Of course, she knew most of what the moon had to offer. She had helped make it after all. She jumped lightly, wings flapping just enough to give her an extra boost. She soared through the air, looking down.
Normally, this would have been fun. She would have reveled in flying without flapping. She'd never been quite as strong as her sister when it came to actual flying, but this would have let her feel that way. Instead, she felt empty inside, like something was missing.
As she landed, she kicked up a small cloud of dust, which she breathed away into the vast nothingness of space. Her mind was replaying everything in the last few years. Discord, her bid for power. She cried. The dignified, cool Lunar Princess cried for the first time since...
The first time since Mother and Father had died. And then she realized why she felt empty. She had no sister now. Nopony to comfort her when bad dreams lurked. Nopony to nuzzle her and make her feel better. She'd lost the last family member she'd had left. And why? Because she had been selfish, ungrateful and greedy.
As the Princess turned her head towards her old home yet again, tears streamed down her snout to drift slowly to the dirt of the moon. In a quiet, heartbroken voice, she spoke. "I'm sorry..."
In her time on the moon, Luna became bitter, and had realized some things. You couldn't rely on anypony but yourself. You couldn't count on ponies to help you out when you needed it most. If you were, say, corrupted by a force of evil, you would be taken care of right along with it.
These thoughts harbored the entity that called its self Nightmare Moon. As Luna had these thoughts more and more often, Nightmare Moon became more and more powerful. And finally, Luna found herself completely trapped, watching as her body was transformed and taken control of- true control, not like before.
Nightmare Moon shoved her off to the side and locked her in her own mind, unable to resist. And now, she was isolated from even herself, unable to t hink or act on her own. Nightmare Moon revelled in the feeling of power, and began making preparationgs in order to destroy Celestia when they got back to Equestria.
"And now, we play the waiting game."
