Warning: The following story is currently unedited.

Canterlot. Once upon a time it was a golden city where it was the beating heart of Equestria's culture, power, and wealth - now abandoned. After magic was lost and the three pony tribes separated, it is long assumed that Canterlot was simply a mythical place - a legend where it probably didn't exist. Or if there were such a place, then it's more than likely that nopony has lived there for a very, very long time.

Nopony lives there anymore... Except for a very old unicorn. Who long believed that he might be the only pony left in the whole world. He passes the time by recovering and recording whatever music he could find. A Music Catcher of sorts.

His name is Inverno. And this, is his story.

Edger Allegore Poeny is a poet and social commentator, but when his agent discovers a hidden group of horror stories and publishes them, Edger is met with growing acclaim. He is invited to Ponyville to perform a reading of not only his work, but also his poetry. However, when he arrives, Edger can't help but notice that some of the ponies there bear a striking resemblance to characters in one of his stories.

(This would fall under the category of 'slow burn horror', where the horror builds only slightly until the very end. This also falls under the category of "Gothic horror" given its focus on atmosphere to evoke a sense of despair, rather than exclusively on action.)
