This story is a sequel to Discord in Hell (Not Literally)
In a universe where things went differently, Twilight Sparkle reports to Princess Celestia on her findings regarding the death and subsequent apparent re-emergence of Discord. This is a sequel to "Discord In Hell (Not Literally)", although really more like a prequel; that story is mature-filtered for a reason and this story will probably make little sense without it, but this story, while dark, is not explicit and therefore some people who prefer not to read mature fics might see it on their feed.
