Existence is pain. Blame Shadowninjaman for my insanity in trying to re-write this. Please search for the non-old and cancelled version. Because I repeat, I'm insane. And so is he for managing to convince me.

Note: It's not up yet. Kinda jumped the gun here, but meh, enjoy this remnant I suppose!

This story is a sequel to Failure of Friendship

Thanks to the events of Anon-A-Miss, Sunset is no longer a Canterlot High School Wondercolt. She still desires to finish her studies, and accepts the assistance of the Sirens in getting enrolled at the other school in Canterlot, Crystal Preparatory Academy. There, she has to deal with all sorts of new drama, from faces both new and familiar, as she struggles to not get wrapped up in the status quo of the Academy.

Idol Hooves holds a special place in Equestria. He's probably the only exiled changeling to serve in the Royal Guard, or at least, that's what he expects, as exiles don't really broadcast that fact. However, it's well known that Princess Celestia loves all of her little ponies, and her guards perhaps more so, and that makes it one of the best ways for a changeling to discreetly feed.

But how does a changeling even get there, let alone get exiled in the first place? For that matter, why would it ever go to Canterlot? Set a number of years before the series proper, before Luna’s redemption, Idol details how he was exiled, the ponies he’s met, and the series of misadventures that led him to joining the Royal Guard, and should continue a good ways into the series, as something of an alternate perspective.

Soon, he’ll have to deal with a boisterous new princess to serve and a royal wedding in the works bringing a third to power. Will his old instincts bring this new life crashing down around him? What precipitates Chrysalis’s ill-fated assault on Canterlot? Is it really so wrong for a changeling to enjoy good craftsmanship to an obsessive degree?

And changed the character tags a bit.

The failed invasion of that mad queen, Chrysalis, rocked the changeling community. From the hives nestled outside Equestria, to their kin living in peace within, they watch those colorful ponies eye one another with suspicion and let themselves be swallowed by fear and distrust.

A gamble by Princess Celestia has summoned forth the diplomat to the Seekers, the one changeling who may be able to ease tensions between their races and restore balance. The Bearer of Magic has been summoned after a century of peace.

And, like her mother before her, Princess Twilight Sparkle will answer the call.

This story is a sequel to Breaking Out to Avoid Being Broken In

Chrysalis has had better days. In fact, she once had it all. A loyal horde, her enemies cocooned as sources of food for her hive, a home not cluttered with useless items like banners, doors, and toilets. Times have changed for the former Queen and she’s going to have to figure out how to adapt to her new life. Or, you know… do something sensible like try to get her old one back.

Mature version here. Warning: This version contain graphic descriptions of actual pony and changeling sex. Proceed at your own caution.

Silver Spoon’s day doesn’t go like any other. Her friends on the household staff treat her more like their boss, rather than their friend; Her three best friends no longer like her for some reason, and the biggest and most arrogant school bully who has been tormenting her for years is acting suspiciously friendly towards her.

Silver Spoon’s day doesn’t go like any others. The house servants are more talkative and more friendly than ever, no longer acting as formal and professional as they should. Three blank-flanks keep inviting her to spend time with them for some reason, and her best friend Diamond Tiara… betrayed her in worst way possible.

Something is clearly wrong.

How will each Silver Spoon survive such a big change in their life, and how will everyone react to their change of attitude? Only time will tell.

For a massive revision/proof-reading of the story.

This story is a crossover between MLP and Alan Ituriel's Villainous.

Black Hat has been notorious for quite a lot of things over the course of his long lifespan, many of them rather diabolical. Considering this, he would likely not have anticipated that it was one of his more petty indulgences that would trip him up in the end. However, releasing a mocking ‘lost files’ video sassing an embodiment of chaos and disorder for his reformation at the hooves of pastel ponies was probably not the best idea. Then again, nobody had ever accused Black Hat of wisdom.

Discord, needless to say, was not best pleased by the horror’s razzing, and decided to take matters into his own claws. What Black Hat failed to take into account was that, while silly a lot of the time, Discord possessed fewer of the limitations keeping him in check, and a penchant for warping the existence of others.

So Black Hat scoffed at the notion of those pastel ponies? Why not make him dependent on their saccharine sweetness to feed? A changeling, after all, could hardly deny the value of love. The idea was quite appealing, and while Discord was now under expectation of not causing havoc for Equestria, someone from outside couldn’t possibly count, could they?

Discord seized Black Hat while the horror was asleep and drew him into the world of the pastel ponies he’d so mocked, altering and binding him into a new shape - that of a changeling egg, in a hive just far enough in the past that he thought he'd be able to enjoy the entertainment in the present without having to wait. He couldn’t make the change total, some aspects of Black Hat’s nature too intrinsic to remove, but he could make sure the new equid could not simply shrug off the change. Stranded in an entirely different life, Black Hat would need to learn how to live it.
