It's Flurry Heart's seventh birthday, and her parents have told her she can have anything she asks for (so long as she eats all of her crystal veggies, which she did). They expected something extravagant, but obvious - a fancy dress, a room full of candy, maybe even her own little throne between theirs. What they did not expect was the one thing she wants more than anything for her special day. Princess Flurry Heart... wants a pony of her very own.

[EDIT]: Wow, on the front page in less than a day! This is amazing!

Princess Luna ordered the Tantabus to torture her dreams every night so that she would never consider returning to the dark path she once trod as Nightmare Moon.

Luna should have remembered just how difficult it was for her to obey rules before she used her own essence to create what was, in effect, a smaller, more headstrong version of herself.

The Tantabus is determined to follow the true purpose of her command, no matter the consequences, large or small.

Or very, very small.

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?
