Spike has been missing for three years. Why he disappeared is a mystery to everypony. What caused him to leave in the first place, and why is he suddenly back now? He's acting cold towards his old friends and won't reveal why. He's lost his love for Rarity and is treating everypony he comes across the same way Gilda did.

Opening theme for this story is: Constellations - Sound of the Aviators

Rated: Teen for language and potential sexual outcomes.

Warning: Self-harm is described in this story. If you are prone to self-harm or know someone who is and feel uncomfortable reading about the subject, then I don't recommend reading the story.

After GLaDOS is uploaded into a potato battery, Wheatley humiliates the AI even further by uploading her into a project that was abandoned by Aperture a long time ago. In the blink of an eye, she finds herself in a deformed body of flesh and bone that resembles an equine, and is just as powerless as one too. It comes with all of its needs and bodily functions as well. To make matters worse, she's trapped in a land full of insufferable creatures that just want to make 'friends.' Will GLaDOS' cold, sadistic sense of humor and morals get the better of the ponies? Or will they peel away the once artificial being's metallic shell and find that there's a softer side? Probably not, but it's worth a try.

Story Theme: Tyler Bates - I Love You (Watchmen OST)

A girl with indigo hair landed in my shower in a flash of light, can use magic and claims that she is, or was, a pony...and says I'm the crazy one. I promise, I'm not. Though her elitist little mannerisms might just drive me to kill her, we'll see if we can get her back to her home before that happens.

After her disappearance three months prior, Rarity finds her way back home. Of course, this raises several important questions. Where was she? What did she do? Why is she wearing bloodstained armour? And who is this "Wanderer" she traveled with?

A not so standard human-in-Equestria story including but not limited to: democracy, tequila, and robots.

Things escalate from there.

Every department has them. The standouts. The supercops. The other guys. And for some reason, there's always one or two of THEM... a pair of loose-cannon cops who refuse to play by the rules, taking the law and throwing it in cuffs right alongside every mook and petty criminal they've apprehended on the mean streets of Ponyville.

These are the reports of two such officers in the Ponyville Police Department, Officer Cherry n' Berries and Officer Dodge Charger. Two officers that seem as determined to uphold law and order in town as they are to rip the place to shreds, upholding the hell out of law and order in town.

The Pillar of Autumn wasn't the only ship that left Reach when the UNSC withdrew from the planet. The UNSC was desperate to find a planet to settle on where they can effectively hide from the covenant and recover from the near fatal blow they suffered on Reach. When the Hall of Heroes, a ship similar to the Pillar of Autumn only smaller, finds an unexplored planet away from the covenant empire, they
immediately launch a recon mission to confirm if the planet is habitable, Mikel Dakre and his ODST team find more than they bargained for.

"Is anypony out there? Please, my name is Trixie! I need help! I think... I saw a cockatrice. I can't move, I can't see. Please, somepony, anypony.... Help me."

Laid low by circumstances beyond control, trapped in a cruel and unrelenting prison of flesh made stone, can anypony hold out hope to see the day once more? When their life rests in the hooves of one whom they tried to humiliate and belittle, can they trust in them and make it right? When they can only see through the eyes of another pony, when only one other can hear them, can they stay sane? When the only chance for their freedom is a fool's hope made incarnate, the impossible made improbable, can they beat the odds? Trixie is going to find out.

Pride can lay one low. Stubbornness can leave somepony friendless. Anger and Sorrow can turn others away. And yet, they can give strength. And Hope, in the darkest hours.

If you're afraid of Dark tones, or find them distasteful, or can get stabbed easily in the feels, I suggest reading on only with caution. This is not a happy tale.
