There are three types of people in the world..Comrades who fight alongside you.
Non-Combatants who you avoid killing when possible.
And Hostiles who are to be dealt with using lethal force
-PFDR training manual, author CDR Twilight Sparkle
Two months ago Twilight Sparkle disappeared during a teleportation experiment. Everypony was beginning to lose hope of ever finding her. Then one day during a Bugbear attack in Ponyville Twilight resurfaces and single hoofed defeats the Bugbear with powerful weapons at her disposal.
Her friends are happy to see her but something is wrong. For one she says she's been gone for over six month and the fact her eyes are not natural and her legs are made of metal.
Gone is the peaceful librarian, she died months ago, in her place is Commander Twilight Sparkle, a mildly unstable, slightly sadistic, highly militaristic, highly intelligent, heavily armed, well trained, heavily augmented mare of war with a questionable sense of morality.
This is her story, how she went from a caring and slightly awkward mare, to a mare with no qualms about handing out death just as likely as she is to look at you.
Best to stay on her good side.
Note: These chapters are uploaded unedited and I will slowly do minor edits here and there and once the story is complete I will have major edits done. I am focusing more on writing the story so as not to lose my motivation to write.
Note2: This is an alternate earth that has some things similar to our own but over all is different so how people behave will be different then our world.
