Fallout: Equestria

"I'm sending your students to the Moon!" Celestia said.
Luna felt as if the air was knocked out of her.
Surely she can't be serious!
Of course Celestia was joking that day.
Now there was a beautiful shiny new school waiting in the Crescent Moon Valley - and Luna couldn't ask for a better place. But as the first students boarded the train that will take them there, her heart was heavy.
For one last time she checked everyone was on board.
Then turned to her sister, to say goodbye.
Celestia hugged and nuzzled her: "Take heart, Luna. You'll do great."

Dear Luna,
you know there has never been a more devout fan of Wonderbolts than me, right? I'd never dream of diminishing what they did for Equestria. They always were, are, and will be the heroes.
However, your task for me was to build a new offensive aerial unit.
I chose to name them Shadowbolts, partially in homage to you and partially because Rarity tells me it will play up nicely on the Zebras' superstitiousness when it comes to Nightmare Moon.
We'll need every edge we can get to achieve victory.
Fear not, I will not fail.

Caravan with irradiated water was flying across the Everfree, protected from the dangers of the Wasteland by two Talons. Suddenly several pegasi raiders sprung up, surrounding the group.
"Oi, mercs," one of them, sporting a magical shotgun called. "I'll double the caps them lot are payin' y'all fer protecting 'em, if y'all join me before the shooting starts."
The younger griffin looked conflicted: "Reg, how do you wanna play that?"
"By the word of Gawd, Buckbeak. Talons' loyalty is to the contract and to the caps - in that order."
She took aim with her crossbow.
"Keep calm and open fire!"
