The End of Days has come to Equestria. The Four Stallions of the Apocalypse ride across the realm. Twilight Sparkle finds a way to safeguard the kingdom, but it will require a grave sacrifice... and some help from her friends.
The happy end is debatable here. Twilight did warn the other princesses in time and now have some form countermeasure. However, the very end implies that Twilight abandoned her friends to a corrupted Equestria while she holed up safe in Canterlot. She may be looking for a way to rid all of Equestria of the corruption, but how long will that exactly take? If it takes to long, than their lives would be lost and wasted to the corruption. I honestly see suicide as a possible end for many ponies after Twilight succeeds in reversing the corruption.
I don't see anything happy about this end. All incredible gifts are lost forever. No hungry butts! No bestiality 24/7! No incest! No foal whores!
