The date? Unknown, we lost track.
Rulers? Princess Celestia and Luna were assimilated and killed months ago. King Discord sacrificed himself for Fluttershy. Princess Cadance and Prince Shining Armor fell with the Crystal Empire. We have nobody.
Elements of Harmony? All of us are dead. Except for me.

My name is Twilight Sparkle.
Sunset and I are the only ones left in Canterlot now.
A survivor came by once. We didn't know whether to consider him lucky or not.
He looked at Sunset with pure fear in his eyes.
By morning, he was dead. His throat had been slit.

...
Something's not right.
