"My handsome little cherub, close your eyes.
Mommy's going to give you clear blue skies.
So you’ll laugh and dance and play in the air.
And sing the song of angels everywhere."

After receiving an urgent letter from Princess Celestia concerning a grave danger to Equestria, Twilight Sparkle undergoes a crisis of faith. Can she perform a grim task for her beloved mentor, even if it means sacrificing all that she cares about?

Based on a story prompt by TraleRayne. Extra special thanks to Dream of Ponies and Noble Jury.

In a dark place named Tartarus, a subterranean hellscape between worlds, humans and ponies are paired together at random to survive a gauntlet of horrible monstrocities while the future of their realms hang in the balance.

Now, are you buying that? Good. Cuz I'm friggin' tired of having to explain it all on top of dragging this annoying-ass unicorn around the effing corridors of purgatory along with me. You'd think the damn, burning yahoos who run this place would give us rest stops to drown ourselves in beer or something. Friggin' A.

Oh, and some ponies and humans spill blood together and stuff. I dunno. Stop playing BattleDuty: Future Football and read this, or whatever. Like I give a crap...

What do we truly fear in death? Can an ageless alicorn keep a promise to her beloved?

Can she remember who Rainbow Dash was?

Not everypony wants to get their cutie mark.

Sometimes, when I'm writing, I get upset. I have occasional psychiatric problems, and my creative work means a lot to me. When it doesn't go just right, I can get very emotional very quickly. Enough that sometimes it worries my friends, and they ask what's going on in my head.

This is a story about how it feels, as told by little horses.

Something hasn't been right about Rarity since the Inspiration Manifestation spell. Maybe somepony should check on her.

Now with a reading by Dr. Wolf!

Sky Stinger thinks that the Holy Grail is hidden down his toilet. He must get it out to win Vapor Trail's love!

It's been a long time since Trixie Lulamoon could call herself "Great and Powerful". After her humiliation at Ponyville, she searched far and wide across Equestria, looking for some way to restore her reputation and shore up her pride.

Lucky for her, Princess Luna has decided to re-open a very special division of the Guard: The Dreamguard. Trixie was only one of many to apply, but she was the very first to be accepted. Now she has a roof over her head, three square meals a day, and lessons in dreamwalking taught to her by the Princess of the Night, herself!

As far as Trixie is concerned, life couldn't be better. But the Dreamrealms have wonders and dangers all their own.

A side-story to Project Sunflower: Harmony, though no prior reading should be needed to read this story.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.
