A playing at a private estate was hardly unordinary for Octavia, despite how early in her career she still was. The murder of a groom to be right after their engagement? Less so.
A crew of 4 tankers, strained with little to no reinforcements, behind enemy lines, only to prevent a full-scale attack that saved the lives of thousands.
Princess Nightmare Moon had tried to keep it secret. She had feigned ignorance, but the charade could not last. She nocked the arrow. Tirek was a large target; he would fall easily. Then the true challenge would come: explaining herself to Celestia.
She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly. Black streaks ran through her mane. Worst was the scar across her chest. The tarnished Celestia smiled at Luna. "H-hello, monster."
For most humans, being sent to Equestria and put into the body of a megalomaniacal centaur trapped in the depths of Tartarus would be the most bizarre thing that ever happened to them. For a certain knife-wielding mercenary, it was Tuesday.
Nightmare Moon won. She defeated Celestia, broke the Elements, banished the sun. This all happened a very long time ago. So long ago, that she has had plenty of time to change her mind. Not that fixing it will be simple.
