The story of 'The Mare that eats the Monsters' is an old, but still very well known Equestrian campfire and bed time story, often told to scare little fillies and colts into behaving themselves. It tells of a mare who loves Equestria and the ponies who live in it despite how frighteningly different she is. She protects ponies across Equestria from nightmarish creatures and monsters that would seek to kill ponies wherever possible.
What most ponies don't realize, but what Twilight Sparkle is soon to learn, is that the mare of the story was and is very real.

And the stakes of her mission have never been higher.

(This story has the horror tag, yes, but it isn't the dominant theme here.)

One early morning Twilight is woken up by the sound of somepony knocking on her door. To her surprise she finds Rainbow Dash on the other side, only the mare seems off. Disgruntled and panicked, the more she talks, the more Twilight is convinced there's something wrong. What happened to her?

One night, Twilight notices something odd as she's nestled in bed with Rarity: her hair smells different, just slightly. The next morning, her tea tastes a little bit less sweet, and the flowers outside smell somewhat less fragrant. Out at a cafe together, the music doesn't sound as sharp and clear, and Rarity's new dress feels marginally less smooth against her coat.

Twilight just wants to know what's happening, so she can fix it. It has to be temporary, after all.

This story is a sequel to Meltdown

Twilight Sparkle struggles with life, loss, and sickness after having saved Ponyville from disaster. The day she asked Rainbow Dash out on a date, unsurprisingly, did not go according to plan. Now that she's recovering, she has to deal with the results of what happened, regardless of whether they are good or bad. At least she has the support of her friends, and perhaps, somepony more than just a friend to help her.

There's a dark secret behind all of this, and in a journey that heralds only pain and turmoil, does Twilight really want to know the truth? Or are some things best kept close to a pony's chest?

I am not really familiar with Twilight Rarity ship stories, but I tried my best and hope everyone will have at least some fun with it. ^^

Twilight, on her new wings, couldn't find her way around Cloudsdale. It may have left more of mark on her than she wants to admit.

Maybe she could use some help, but she's going to have to be honest first.
