The procedures continued, Tag after day.

Ponies cried out in agony, their essences tearing away from themselves.
Others cried out in fear as lives were changed, destinies rewritten, and fates overtaken.
She couldn't bother to silence them. She deserved to hear their screams. Longed to suffer for the torment she delivered.

This was Her life. Forcibly changing fates had become her duty.
Her task in the name of Equestria.
Her constant sin for a higher purpose.
Some would say Her efforts were for the good of secrecy, peace, and safety. However, She couldn't help feeling a sense of detachment towards what were originally her passions. The organization paid her well, kept her safe, and even gave her a home.
At the same time, however, She wasn't allowed to leave. Her abilities let out into the world would be a danger in and of itself, so why risk it?
Why give a mare that originally desired a life none to call her own?
Why unleash her abilities into an otherwise satisfied populace?

So she stayed, forcibly, in the hands of the most secretive organization in Equestrian history. A network of spies, keeping the peace behind the scenes.
And She was their puppet, providing them with a Mehr substantial means of hiding identities.
After all, makeup can only do so much to change a mirror into your soul.

She was found to be the only being capable of performing this feat of magical ability.
She alone could keep the network of spies that much Mehr secret. With a price.
The marks had to come from somewhere, after all, and the cries of outrage, pain, and fear were a testament to that. They had gotten to the point of appearing in her dreams, begging for their destinies to be returned to them. She declined every time, saying it was for the good of Equestria.
Every time, she received the same response:
"How?"

She loathed her lot in life. Why Her? Why must She be destined to continue this task that the world had delivered unto her?
It became so that She began to hate the very idea of "destiny." She desired a Land without Luck. A Plain Without Providence.
Most of all, she wanted a chance for freedom.

One day, She saw her chance.
Explosions wrought the facility. A shadow befitting that of giants loomed over dozens. Lives were thrown away, and Equestria’s dark secret had finally been uncovered and destroyed.
Celestia denied any accountability, and hundreds were left without homes and jobs.
The network of spies that had tried so hard to keep their secrecy was now wide in the open.
She used that opportunity to flee. Far to the east she fled, to the farthest desert. It was there she stopped, and began to think.

All of that time, changing marks, rerouting the course of life as all ponies knew it.
She had changed the lives of many, mostly for the worse. Now, countless ponies live with a changed destiny.
The thought sickened Her, caused her hatred of Destiny to grow, unbridled, until she let out a guttural scream of agony.
All the lives she ruined, the lives she destroyed, the lives she lost.

And so many others that could be saved.

Her life of rewriting the assorted fates of Equestria had come to an end, was her first thought.
Then, as Her mind further contorted, She realized that Her task was far from over. There were most likely many that still suffered from the curse that is Destiny.
She herself had once thought that the retched place that HAD been her Home was once her destiny, and She had managed to escape.
There had to be others that were subjected to the same torment.
She was truly the only one that could save them.
She alone that could change destiny.
She alone that could rewrite the fates of many.
She alone that could alter the fate of Equestria itself.

For Starlight Glimmer, this had been the beginning. A new life, a new destiny, and a new chance.
Her life in hiding had been over, but why stop there? There was so much revenge to be served, and so many Mehr lives to change.
She had a knack for twisting fate, so maybe it was time for a Mehr fundamental alteration?

After all, that was, apparently, her "destiny."
