"Sunset, you weren't the first unearthly threat to come to this world, and you won't be the last. If we seem calm in the face of strange events, it's not because we're oblivious or indifferent to them. It's because they're not strange to us. The Fall Formal may have been the most important night of your life, but to us... it was Thursday."

(Slice-of-life adventures of Canterlot High's unlikely band of monster hunters.)

This story is a sequel to Honey Pie II: The Wrath of Chrysalis

Sweetcake has come far in life. From a defeated drone, stranded alone in Canterlot, he's become the queen of a large and powerful changeling hive. And he's doing a surprisingly good job at it. He even has time left over from his royal duties to help Pinkie Pie with her parties. Unfortunately for Sweetcake, Pinkie, and the entire hive, his hive is not the only hive out there, and the others don't approve of allying with ponies. Caught between betraying his friends and the welfare of his subjects, any choice may spell disaster.

This story is a sequel to Somepony Tries to Sell Twilight Insurance

Ponies were very surprised when Jackpot Enterprises' managing director, Crystal Jackpot himself, started allowing Ponyville's richest residents to insure their properties with his company - not least because the last thing anypony ever expected was that Jackpot Enterprises would do something enterprising. However, they were even more surprised when a crippling blow was dealt the idea by none other than Princess Twilight Sparkle.
Not only did she not have her castle insured: she also urged every single one of her friends - her rich, powerful friends - not to take insurance out either. Nopony would suggest that Jackpot was a resentful stallion - nopony who didn't want to find himself homeless within the week, anyway - but it was, all the same, surprising for Twilight when just about everypony she knew took out insurance against, er, her.

One day, Twilight Sparkle discovers something amazing about her friend Sunset Shimmer.

She's a magical talking pony!

This requires investigation! Science! Possibly a full-body physical!

Or maybe Twilight will just ask her what's up with that.

Rated Teen for frank discussions about... y'know.

Sunset Shimmer loans Pinkie Pie a thumb drive.

Except that it's the wrong thumb drive. And that it contains exactly what you'd expect to find in the wrong thumb drive to loan away.

Rated Teen and Sex for discussions of pornography and self-love.

This story is a sequel to Sunset Shimmer Lends Pinkie Pie the Wrong Thumb Drive

Sunset Shimmer visits the Castle of Friendship, and inadvertently discovers something that Twilight would normally keep hidden under her bed... except that since this is a pony princess we're talking about, it's obviously nothing remotely resembling normal.

Rated Teen and Sex for discussions of pornography and self-love.

Twilight Sparkle has always been frustrated with Discord. His ability to do anything, with no more effort than a snap of his claw. It shouldn't be possible. His power had to come from somewhere.
Then, one day, Twilight lets slip how she feels. Surprisingly Discord agrees to explain it to her. To give her the secret to all of his powers. If she's willing to pay the price that knowing it all will bring.

This story is a sequel to Twilight Sparkle of the Royal Guard

Between castle gossip, professional rivalries, a blooming romance, and a mysterious malefactor still at large, Decurion Twilight Sparkle has a lot on her plate. Hopefully, she'll make a few new friends as she moves towards the destiny she's chosen for herself.

As per usual, big thanks to Magello for the rad cover art!

A flip of a coin. A twist of fate.

Twilight Sparkle, younger sister of Princess Celestia's personal student, Shining Armor, grew up listening to her brother's bygone dreams of joining the elite of the elite: The Royal Guard.

Now, fresh out of the Academy, this young mare is ready to prove herself equal to the deeds of the great soldiers she read about as a filly. Too bad the princess she ends up protecting isn't Celestia.

Sweetie Belle gets stuck in a time loop.
