I have always been alone in this forest. I have always feasted in this forest. I call this forest home and those ponies that travel through it are my prey. I devour all those who fear me, all who come to face me. They fear me for I am Fear incarnate. But now...I have met one who does not fear...and I am unsure of what do with her...

The Great and Powerful Trixie turns to radical politics.

It started out as an ordinary day for Fluttershy – waking up in her house in Cloudsdale and going to work managing the weather for Ponyville alongside her best friend Cloud Kicker. However, she finds herself troubled by feelings she can't explain, feelings that something serious is wrong. When she starts having visions of a strange life with strange ponies, she's determined to find them and find out what's going on. But how can such a timid pony convince others of what she isn't sure of herself?

Things couldn't possibly get any worse for Rainbow Dash. Her job is falling apart, she's convinced that she's made her friends hate her, and even her dream of some day joining the Wonderbolts is in peril. While things are looking pretty bleak for Ponyville's coolest pegasus, her best friend and kinda-sorta fillyfriend Pinkie Pie is determined to whatever it takes to help her, and she's not going to quit until she can put a smile back on Rainbow Dash's face.

This is a side-story of "The Life and Times of a Winning Pony" which occurs after the events of Chapter Ten of that story.

A thousand years ago, in the magical land of Equestria, there were two regal sisters who ruled together (basically) and created harmony for all the land (well, mostly).The two sisters maintained balance for their kingdom and their subjects, all the different kinds of ponies (it's a little more complicated than that). But, as time went on, the younger sister became resentful. The ponies relished and played in the day her elder sister brought forth, but shunned and slept through her beautiful night (generally speaking, but you know, that's not exactly the whole story).One fateful day, the younger sister refused to lower the moon to make way for the dawn (okay, you're skipping over a lot of details here). The elder sister tried to reason with her, but the bitterness in the young one's heart had transformed her into a wicked mare of darkness! Nightmare Moon! (Okay, this is getting misleading) She vowed that she would shroud the land in eternal night. Reluctantly, the elder sister harnessed the most powerful magic known to ponydom: the Elements of Harmony! Using the magic of the Elements of Harmony, she defeated her younger sister, and banished her permanently in the moon (whoa, hey, now you're skipping over, like, everything important). The elder sister took responsibility over both sun and moon, and harmony has been main- OKAY LET'S BACK THE HELL UP RIGHT NOW SHALL WE.

Okay, look, that's all technically true, but a lot of information is missing. So, let's get the story straight.

This is the story of a powerful pony who must face her faults when her strength fails her. This is the story of a teacher with lessons to learn. This is a story of love and of hatred. This is a story of joy and of sorrow. This story does not have the purpose of instilling a particular lesson -though it has many- or bringing about a particular feeling -though it has many of those too- like so many stories do.

This is just an Old Mare's Tale.

This is a story I actually began, like, a year ago. Somewhere around fourteen chapters are up on EqD and Fanfiction.net. Now that I have resumed work, I've decided to post it to FiMFiction as well. It's not been on FiMF before, so this is NOT a re-post.

Though the content of this story does not cross over into Mature territory, there is some graphic violence, and certainly some immature allusions (okay, and they straight-up talk about sex, too). Plus, there are swear words. If you are worried about that sort of thing, then this may not be the story for you. I know this warning is a bit redundant with the content rating, but I feel warning redundancy is a good thing.

To save her sister and her faithful student, Celestia herself must travel into the ancient tunnels beneath the ruined castle in the Everfree Forest. She, and the guards who accompany her, must face the dark, twisting corridors. Still, what was Luna and Twilight's purpose at the old castle? Why were they unable to return of their own accord?

And what watches Celestia from beyond the light's edge?
