If you haven't read New Reign, please do so. This is only a side story, created separate from the rest of the story because I didn't want to add the Gore tag to New Reign.
If you insist on reading this without first reading New Reign, some backstory, but not enough to give spoilers to people who still want to read New Reign.
A group of 40 guards entered a warehouse, prepared for anything... or so they thought. This is the story of the Maripony Massacre, where 39 guards and their captain enter... but only one comes out.
Special thanks to TripleRainbowDasherXXX for requesting this side story.
