At first glance, Princess Luna's charioteers might appear to be little more than Royal Guards dressed in festive apparel for Nightmare Night. However, there is far more to the story than that - the Night Guards once played a pivotal role in the history of Equestria, and have sacrificed more for their beloved princess than most ponies are even aware of.

Updates: Weekly, hopefully.
Don't think about this too much, it hurts the squishy sponge.
WOO, FEATURED! 18.1.2020

EDIT: Added a character cheat sheet in the bottom of this section due to requests.

The only thing that's known about changelings in general is that they came from the Badlands and that they eat love. Oh right, and that their queen is evil, cool, and certainly does not star in some of the wilder pony dreams.
Not much, is it?
The thing is, it's not as if they know too much themselves. For example, how many of them there really were? How many of them survived the invasion? How silly was it to attempt to disrupt princess Celestia's cake supply?
No one can fully answer such burning questions. Only one thing is for certain - they're now everywhere, and they all have their own stories to tell, some long, some short, some violent, some silly, some happy. Changelings all over the place.
Not every creature minds, though.

Rainbow Dash is the coolest and fastest pony ever! Everything is going her way lately! Nothing can stop her!

Though she is starting to feel not so awesome. Her mood swings a lot, she doesn't feel too well, and she has gotten some strange food habits.

Rainbow Dash is pregnant...

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?

Echo the bat pony has no qualms about stealing mangos from her housemate. However, when her serious lack of self-control causes things to escalate far too high, certain powerful forces decide to punish the greedy bat pony by placing a curse on her. This curse will render her unable to ever eat another mango again through various , and often implausible, means.
But even though the universe itself is against her eating a mango, it won't stop Echo from trying to regardless.

Things are hard in Ponyville for Fluttershy and Discord; mainly because of Discord. But when magic starts to go on the fritz and eventually starts failing altogether, it's up to the main six and the Draconequus to find out what's causing it and, more importantly, how to fix it.

This would be a lot easier if anypony trusted the King of Chaos to begin with, but with bigger problems on the horizon, some things will have to wait to be dealt with. Like trust. Or loyalty. Or friendship.

Of course, sometimes what we think isn't important to deal with right now, is exactly what's needed to prevent things from getting far, far worse.
