Just about everypony in Equestria had heard the story. Every now and again, and always at around midnight, a phone call would be placed from the Greenhill Resort, a closed down resort between Ponyville and Canterlot, to the Ponyville Ambulance Company, a company based in a run-down, barely functioning garage that houses two ancient ambulances to arrange a pickup of a "patient(?)" (identity unknown) from there, and take them to the Old Hollow Hospital, a decommissioned hospital outside of Canterlot. Nopony knew why these runs were needed, where these supposed "patients" were coming from, who they even were, why they were at a closed down resort, why they were being taken to a decommissioned hospital, and who was making these calls at all. Some had asked those at the Ponyville Ambulance Company what was going on, but none of the 3 employees there said anything. Most thought it was because they were tight-lipped, but in reality, even they didn't know what was going on, but they knew that something shady was afoot. This is the story of one of the fabled "Midnight Runs", and the mystery surrounding it, told from the perspective of one of the ambulance drivers
(Story contains no direct horror elements, but is still a bit spooky, and surrounded by mystery. Rated "T" for these elements)
