Twilight has something she needs to tell Princess Celestia--something that means a chance at getting everything she's ever wanted, or of losing everything she's ever had.

Something so terrifying that the only way she could say it was in a letter...and so wonderful that she had the courage to send it.

(Thanks to Cenit V for the cover!)

The Mirror Pool is a dangerous tool and after being asked by Princess Celestia our heroine Twilight Sparkle finds out what problems can arise from such strange magic. When a creature of little inhibitions and great magical power is released on the small town of Ponyville what can our stalwart friend do to stop her.

How can you stop somepony who knows you better than you know yourself?
Twilight Sparkle...meet Evil Twilight Sparkle!

When Cheerilee puts adventurous Scootaloo with fraidy-pony Twist, shy Sweetie Belle with outspoken Silver Spoon, and complete opposites Apple Bloom and Diamond Tiara, the Crusaders don't think it could get any worse. But while working on the project, the pairs get stuck in a snowstorm.
It's not the sleepover they want.
However, they might end up with a whole new perspective on their opposites.

(I kinda setup my own rules on changelings logic. So if there are any other changeling stories that have different logic, I won't follow it.)
[2nd POV] A changeling is a mindless slave, and was only born to serve Queen Chrysalis. It does not have feelings, so it does not feel remorse. A changeling cannot think or choose for itself, as it is not sentient. It only moves without question, and only constantly feed off of the love of ponies. Since it is not sentient, it cannot be befriended, cannot learn to communicate, and cannot feel love. Its sole-purpose is to feed off love out of every pony alive.
But... that doesn't seem to apply to you.
The day you met that one unicorn, was the day you began asking, questioning your own existence.
Ever since the fall of Queen Chrysalis, she was nowhere to be found. Your siblings can't seem to do anything without her guidance, and slowly, each one of your siblings begin to die out. As an endangered changeling in hiding, you use your newly discovered free-will and wits to try to find out the answer to your question. Trying to solve it before you die. "Who am I now?"
(I guess now that i think about it, I just made changelings the equivalent to zombies. And you are a.... Sentient zombie?)
On hiatus for the moment. Until I get my shit together, this story is going to just linger there for some moments.

Snips and Snails decide to write a shipfic about their two all-time greatest heroes, the Great and Powerful Trixie, and Rainbow Dash. Because that's what fanboys do.

Natrually, a true piece of literary genius is produced as a result. They may have even got Cutie Marks for it, had they not already discovered their special talents.

Twilight masters a new spell, one powerful and old, that allows her to peer into other realities. They give Twilight and the others a chance to see what could have been and what may still be in their own dimension.

Shortly after the events of 'Magic Duel', Trixie reconsiders life on the road. She had returned to Ponyville to prove herself to Twilight Sparkle. But perhaps it wasn't for the reason she originally thought.
She returns once more to finish patching things up with her but there are other issues at hoof. Twilight extends her hospitality, but there are her many questions about the showmare left unanswered. Where has she been? What did she do while she was away? How did she amass so much wealth in that time?
Trixie has dodged Twilight's scary questions long enough. But the answers may be more frightening still.
NOW SEQUELED!

Apple Bloom and Scootaloo have found love... with the same filly: Diamond Tiara. Neither of them are sure how approach this situation: they both want to win Diamond Tiara's affections, but are they willing to put their friendship on the line to achieve it?

What's worse is that Diamond Tiara can't accept either of their feelings, because she herself has fallen for both of them, and is unable to chose between the two fillies that are slowly driving her mad, both during and after school!

Rainbow Dash is round Rarity's boutique posing for a costume when she breaks a dusty old teapot!
Rainbow just can't understand why she is so mad! Surely their friendship isn't finished over one old teapot?

Right?

Rarity's decided to break up with Applejack, but were they even an item in the first place? And, perhaps more importantly, what does Applejack have to say about it?

Hijinks, of course, will ensue.
