Season 9 is over, but shortly after its end, Twilight and her friends are faced with an even bigger threat, one spanning across the multiverse. This is the story of Equestria's darkest hours, in the midst of the Cartoon Apocalypse.
What should have been a fun weekend getaway to a cabin in the woods turns nasty when a monster shows up. Because of course a monster shows up when a bunch of teenagers go to an isolated cabin in the woods.
After the events of The Legend of The Everfree, Twilight has accepted Midnight Sparkle, and is no longer afraid of her taking over again. But now she’s confused more than ever, not at why Midnight does what she does, but at what and who she is.
