PLEASE READ: This is an old story. Since then, my writing abilities have improved. Please try to ignore any old grammar or spelling mistakes. This story is in the process of being re-written. Chapters may be shorter or longer with info added or removed, so if things don't make sense, bare with me.
I recommend you read only the updated chapters for now. Check back later for updates.
If a chapter has "Old" next to it, it's still in it's original version. Bare with anything that doesn't make sense or anything silly.
If the chapter has nothing next to the title, then it's an updated chapter.
If the chapter has "New" next to it, then it's an entirely new piece of content.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Martin has had an unreal life ever since he first stepped foot into the land of Equestria. He has been regularly visting Equestria and his friends The Mane Six for two months now and their friendship has never been stronger. However after Winter Wrap Up he heads home with The Mane Six directly behind him. Unfortunatly upon doing this, they have not only broken a promise that they swore to Sortitus to uphold, they have also caused the bridge connecting their worlds to collapse behind them. While they wait for a new bridge to be constructed which Sortitus must do by hand (much to his annoyance), the now humanized Mane Six will have to blend into regular society with Martin's help. However things get chaotic when a student from Martin's grad class takes an interest in him and she allys herself with a released Discord who has decided Earth is to be the chaos capital of the universe, and to make matters worse, The Six find out they have maintained there "unique" abilities from Equestria.

WILL DISCORD TRIUMPH?
WILL THE UNIVERSE FALL INTO CHAOS?
WILL THE PONIES GET HOME?
AND WILL ALL THESE THINGS FINALLY DRIVE MARTIN UP THE WALL?

Sequel to Martin: Chronicle Of A Hero

The writer (me) after getting a tooth pulled has a imaginary discussion with his My Little Pony Figures. And it gets weird.

Pinkie Pie visits the local convenience store and discovers Red Pegasus, which 'Gives you WIIIINGS'.

Herein you shall read the most terrifying story ever written and read by Bronies anywhere and everywhere. Cupcakes have nothing on the horror I will bring into your minds with this story. Be glad and pray to Celestia in thanks that this is only fictional.

*Note, this is NOT a Grimdark*

Twilight Sparkle may believe in Pinkie Pie's myriad abilities, but when an opportunity to study them from a perspective she never thought possible arises, how can she resist the chance at the understanding she's always truly wanted? More importantly, can Ponyville survive the trade-off necessary for this opportunity?

You are Knight Watch. You have been a faithful member of Luna's personal guard for ten years, and she trusts you more than most. Things fall apart, though, when she casts a spell on herself.

You find yourself in Ponyville, with no recollection of who you were, and who you are. Making that discovery is just the first step, though.

Prequel to my other stories:
The Color of Apples
I Would Give to You
Faux Pas of the Heart

Luna discovers something hidden from Celestia for twenty years, now, with emotions running high, she enlists the help of the Mane 6... but what seemed to be a single mystery, soon reveals a darker and much more complicated plot that will soon decide the fate of Equestria.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!
