The Shaper is a smith of unparalleled skill, her creations the most sought after in the fallen world. When a pony named Lyra comes to her with a unique commission she has to put all her skill to the test to craft a weapon of great power. For Lyra's goal is not an easy one, and it is not just any weapon that can kill a Dragon.

A story inspired by this and this image, as well as this challenge by CDRW (whose fic A Still More Glorious Dawn Awaits is quite good).

One beautiful morning, Twilight Sparkle decides she wants a free salad. After a small amount of theft, assault, battery, and arson, she sits down to enjoy what is sure to be the best tasting salad ever.

...Or she would have, if it weren’t for the Equestrian Intelligence Service locking her up as a potential threat to national security. Now, Twilight must escape a maximum security holding facility hidden deep underneath Canterlot. And to do it, she’ll need a paperclip, a spymare catsuit, an escape plan, and an alliance with the dastardly Drakbog, King of Frogs.

History teaches us that Star Swirl The Bearded was one of the greatest unicorn mages ever to have lived. But history is notoriously fickle. Was Star Swirl really the stallion everyone thinks he was? What was the secret of his beard? What the heck was the amniomorphic spell? Discover the truth about Star Swirl, and the greatest con in Equestrian history...

Worgen? Try Ponies as the new Alliance race instead! Deathwing's Cataclysm breaks open the seals separating Equestria from the rest of Azeroth, allowing in the insanity that is World of Warcraft and WoW players.

Though many fear her, Princess Luna is responsible for guarding the ponies while they sleep, both from the monsters that creep forth from the Everfree Forest to devour their bodies, and from the nightmare beings that rise out of the Deeper Slumber to devour their souls. As the sun dips below the horizon, Luna readies herself for yet another night of battle.

A new darkness has taken root in the Everfree Forest, and ponies are going missing. Does Fluttershy's new pet hold any answers? Or is Ponyville, and eventually all of Equestria, doomed?

When Spike returns home early from a gathering he sees something that causes him to go running from their little home...the sight of Twilight and Caramel together.

Once Twilight finds him, shivering and cold, she decides to try to address his fears...by giving him The Talk.

But, to Twilight's surprise, it may not be a talk about basic biology that Spike needs...perhaps something far more important is on his mind.

Seriously, a lot.

This story is a sequel to Princess Celestia Hates Tea

Princess Celestia helps to banish a hoofful of inner demons lurking deep in the heart of a troubled author. Metafiction, again, ensues. Something of a coda to "Princess Celestia Hates Tea".

Now with a Spanish translation by Spaniard Kiwi!

Nightmare Moon has won, and the world has been shrouded in eternal night. But hope still lives. The land of Equestria is currently divided between the armies of the usurper and those of the Dawn Militia. However, the greatest danger to the rebellion may not be the dreaded Mare of the Moon, but her lieutenant, Eclipse–formerly known as Twilight Sparkle.
