Inspired by the events from "The Crystal Empire Parts 1 & 2"

Before the war between the Kingdom of Equestria and the Crystal Empire, King Sombra sent a plethora of messages and documentations to Princess Celestia. In short, most of them were proclamations for war against Equestria. After a while, a certain princess grew tired of the constant declarations. As a response, she sent only one letter back to King Sombra...

...And this was what she wrote.
