So begins yet another chilly autumn in Equestria. While making her annual preparations for the winter, Twilight Sparkle comes across four jet black volumes in a dilapidated section of the Canterlot Archives. With Princess Luna's blessing, Twilight begins the long, arduous process of translating the ancient tomes. Before long, she begins experiencing horrifying dreams and visions of distant dimensions and indescribable monstrosities.

This is an attempt at blending the My Little Pony universe with Lovecraft's iconic cosmic horror.
Rated T for potential violence and nihilistic themes.

In an attempt to save face, Big Macintosh takes drastic measures to assure his secret stays safe. However, his actions bring forward a whole new set of deceptions that aren't entirely his own.

(This is the sequel to my featured story Darkest Secrets. I highly recomend people go and read that one first if they haven't already, I'm 99% sure you won't understand the context if you don't.

Bruce Lee didn't die. He just went to a land of magical ponies. Then he solved all their problems.

There are no humans in Equestria. In fact, most ponies haven't ever even heard of a human.

A lone clocksmith is taunted by sleep. Eventually the pony reaches out to a doctor who suggests keeping a dream journal.

Perhaps the nightmares can be explained through good old fashioned psychoanalysis.

Perhaps there is a very good reason you do not remember your dreams.

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

On a warm summer evening, something sinister brews high in the clouds. It is not detected until weather sensors start picking up heavy electrical activity and rain in what seems to be a large storm.

All flights start to divert away except one that is too close, FedEx 715.

The flight enters the storm over Kansas, but as the pilots soon find out, they aren't in Kansas anymore, but instead a land called Equestria that they can't seem to comprehend at first.

How will they interact with locals and what will be the outcome of their sudden arrival?

////// will represent switching from the ATC to the flight. ******is a switch between the flight and Equestria. Other dividers will be created accordingly.

Some abbreviations, such as F/O [First Officer], may be used and will be explained in comments if some don't get it.

After a long day of ruling Equestria, the Royal Sisters need a chance to unwind. Luna's solution is a few glasses of her once famous Moonshine, a drink distilled from moonlight.

Yet, when that one glass turns into several, it's Twilight who will have to deal with the princesses when they’re drunk off their flanks.
