This story is a sequel to Rainbow Factory

That is, until two foals manage to avoid being processed and find themselves in the haunted bowels of the massive facility. Can they make it out of the abandoned factory with their sanity intact? Will they uncover the secrets even a company as dark as the CWC is ashamed to keep? And what of the workers who help ensure that, in the end, not a single soul gets through...

You awaken in a glade outside of Ponyville with no idea how you got there. Luckily, Fluttershy will make you feel better.

Dark, short and annoyingly vague.

The flu; all ponies have had it at some point in their lives. It's a simple yearly ordeal that leaves you feeling crummy for a week or two, then you're fine again, right? Oh how wrong of a misconception that is. This is not the story of the feather flu, this is the story of the black flu; the worst flu pandemic in Equestrian history.
(There is adult SpikeBelle shipping [as in age, not content] and no, there aren't any zombies.)

Though this story is fictional, I'd like to point out that this will be an accurate representation of a worst case scenario pandemic in our world. And after the recent outbreak of H7N9 in China and NCoV in Saudi Arabia, I felt as though I needed to write this story. So I hope this story will both entertain and educate you.

The mane six take shelter in a place that is, for now, safe from a disaster occurring outside.

This gruesome tale of violence and death is not recommended for colts, fillies, or the faint of heart.
