This is a side green to Manos: Hands of Fate by Human Superiority.
The first part was found here: http://pastebin.com/QBMRbrPv
Since Pastebin nuked it I'll also link the earliest thread I could find in five minutes looking in the archive: https://desuarchive.org/mlp/thread/24621019/

For the Manos threads. HEIL MANOS!

>"Forced Changeling Mutations, Murder of innocent ponies using hybrids known as 'hunters', invasive and experimental surgeries, pony augmentation without consent of pony, Brainwashing, Augmenting of Foals for military use,"
>Your face grew pale at that.
>Ponies in the crowd around you started shouting in outrage but you couldn't find your voice.
>It wasn't because your anger had dissipated.
>You've never been this angry at a pony in your life.
>It was the implications of what was happening.
>Manos, the Lord of Fate read on.
>"execution of subjects deemed 'unfit' or as 'failures' most commonly foals..."
>The rest of what your lord said was lost to your own breakdown.
>He couldn't have...
>Looking at the accused, Copper Coin, you could hardly believe it.
>You didn't think Copper ever had a malicious bone in his body.
>You grew up with him.
>You trusted him!
>And your trust gave him the ability to experiment on foals.
>Your stomach lurched and you had to push your way through nearly a dozen ponies to get to a damned trash can.
>None of it got on your Black Hand uniform but it hardly mattered to you at the moment.
>You needed to leave.
>To be anywhere but here.
>Nopony would notice you over what was happening on stage.
>As you get past the last of the ponies crowded around the square you look back for... you aren't really too sure why you did that.
>However, if you hadn't, you wouldn't have caught sight Honor Bound up on stage.
>He was looking straight at you.
>You pretended not to notice his eyes opting to turn tail and head to your home.
>Maybe a nice shower would do the trick.

>You stumbled through the door entering into your darkened living room.
>You fumbled around the wall for a minute searching for the light switch.
>How the heck do you forget where the light switch was anyways?
>You lived here.
>You eventually find it and obviously, you flip it.
>"SURPRISE!!!"
>You poked your head out from behind the couch you dove behind when your wits come about you.
>A banner hanging near the ceiling read, 'HAPPY BIRTHDAY CRYSTAL NIGHT!'
>You stared blankly at the scene.
>You forgot your birthday?
>You picked yourself up put on a winning smile and hoped it was convincing.
>The truth was that any other day you would have welcomed this.
>But not today.
>Not after what you learned.
>A pony like you didn't deserve a party.
>However no pony could know so you played the part.
>"Hey, you got me!"
>Your brother trots over to you and drapes a wing around your shoulder.
>"Sure did get you. Should have seen the look on your face. I'm sure ponies would line up for centuries to see it.
"I'm sure you're just exaggerating, Malachite. Anyways you think mom would mind if I slipped away for a shower? I could really use one but you know how she gets."
>"No no. Go ahead, I'll cover for you."
>With that you, made your way upstairs.
>You couldn't have gotten away from them faster if you tried.
>Your chest felt so heavy it felt like you were being crushed by the judgement of Manos himself.
>You uniform found itself scattered across the bathroom floor.
>Normally it would be on a hanger on the door but you couldn't be damned to care right now.
>With shaky breaths the water came on and steam filled your little bathroom.
>Your throat started to burn as you tried desperately to hold back sobs.
>But try as you might, you failed.
>First came the tears, then you body shuddered and heaved as you lost all of your composure curled upon the floor of your shower.
>But you were silent in your grief.
>Or at least you were close enough to it that the running water drowned it out.
>The faces of fillies and colts flashed before your vision making you curl up tighter. 
>Nopony could ever know you were the pony that made this tragedy possible.
>Slowly you gathered yourself and threw on your uniform and headed down to the party you didn't deserve.
>With that winning smile of course.
>Nopony could ever know...
