Well, when telling a story it's usually best to start right at the beginning and continue on from there. Lets do that shall we? We shall, and you're going to bucking like it!
Ahem...
A mare of stately silver coat writhed under her sheets, her husband no where to be seen, though there was a curiously stallion shaped lump beneath the covers. "Oh Celestia yes! Right there, right th-"
NOPE! NOPE! NOPE! NOPE! Too far back, far too far back.... Just forget you saw that... I know I'd like to. No one should have that image of their mother in their head, now should they?
Lets fast forward a little bit, like oh say nine months or so later? Sounds jolly good to me.
In the fall there was born a lovely little colt, and damned if his folks weren't proud of what they'd managed to bring into the world. Flash Dancer, this colt's mother, was a mare who's coat shone a lovely silver sheen with a mane of bronze. Fitting coloration for a metalworker who specialized in making high end jewelry that usually was formed of those two metals polished till they glowed.
The father of the colt in question was a deep dark color, something in the vicinity of what one would find if the looked at the bottom of a well around midnight. Unlike most ponies, that color was completely uniform for him, a solid black stallion by the name of Onyx Dust. Gems were his thing, and he had a real knack for making things like jet shine like stars. Dark stars, but stars all the same.
As one could guess this made the two of them quite the pair, a couple of ponies who payed the bills with ease due to their combined efforts in making things well worth wearing if one happened to enjoy such adornments. Their cutie marks were even fairly close to one another, both had a ring adorning their flanks, Dancer's made of bronze twined round some dark metal and capped with a bit of obsidian. Dust's was silver studded with little azure stones, the same color as his wife's eyes.
Now as much as has been said about these two, they're really only important in-so-far as bringing our hero into the world. Little Fox-Fyre, the colt currently wrapped in a blanket and held tightly to his mother as she smiled down at him for the first time, Dust looking on with a warm smile on his face. I suppose at this point it should be mentioned that this couple were earth ponies, so it should be a bit of a surprise that they happened to have a unicorn for a son.
Fox-Fyre, being a unicorn, of course had a little nubbin of a horn atop his widdle head. A horn mostly covered by the fuzz of his jet black mane... Well mostly jet black, an electric blue streak ran right down it proud as ya please. It went quite well with his silvery coat, close enough in color to his mother's to look much the same, if a few shades darker.
Now, being earth ponies, it was a bit odd that these two should have a unicorn for a foal, but hey, genetics are kinda weird that way in Equestria. Best not to question these things. Dancer and Dust sure didn't, they were just happy to have a healthy little colt, one who'd likely be turning heads when he came of age. Well, they were right, but for different reasons. He turned heads alright, but not because he was eye candy... That however is jumping far ahead, so that won't be told just yet. What will be told is the trouble one little colt can cause with random magic surges in an earth pony house hold.
A couple months after birth
Fox sat gurgling happily, his horn alight with an azure glow that matched his eyes quite nicely. Also wrapped in that glow were his folks, who were admittedly unperturbed by this. It was a rather common occurrence for them really, well common in so far as they'd quickly gotten used to being randomly freed from the confines of gravity and made to walk on the ceiling for a bit every now and again. In fact theres was likely the only house in Canterlot that needed to have their ceiling cleaned once a week to remove hoof prints. Not something one would normally think to remove from the upper reaches of one's home, no?
"He's at it again dear..." said Dancer with a sigh, her hooves busy fiddling with a bit of gold wire she'd been busy bending into shape for a horn ring some hopped up prince had wanted... Bluebutt or something like that. Whatever his name was, his money was good even if his manners left something to be desired... hitting on a married mare, the nerve.
"That he is... Well, the doc said those magic flare ups would clear up after a couple months, give or take a week... Hopefully this is the last time. I'm seriously considering attaching a chair to the ceiling with how often this goes on." replied her husband with a good natured sigh, as annoying as it was colts would be colts and their little Fox couldn't really help it at this age anyways.
Speaking of which, right as the last syllable left Dust's mouth, that lovely glow around the little unicorn's horn cut out, letting his parents drop unceremoniously to the floor. Fox found this to be very funny, laughing so hard he himself fell over onto his back and rolled about, apparently cruising to bust a gut. Then again, the little fella's point is kind of plain to see, a pair of ponies getting all tangled up with one another and landing with a little "Oof" was kind of funny... Just maybe not so much as Fox found it to be.
Whatever your view on the subject, Dancer and Dust's was that it was worth a laugh, mostly because Fox looked like a four legged silver pill bug rolling about as he was. Dancer made sure to snap a picture for blackmail later on in life. I'm sure if you listen hard enough you can hear the parental laugh of good natured evil. After all, what kind of mother didn't embarrass her colt when he brought home his first date via a photo album?
As far as days went in the house of Dust (as most other ponies called it) that was pretty typical. The three were quite a happy family after all, their days full of laughter and warm love... Sadly, such things can hardly ever last forever...
