Imperium

All that hard work, friendship, lessons and dedication to see Equestria thrive and blossom throughout Generation 4... Gone. I suppose one must honestly wonder what could've happened to cause such an insane turn of events which brought about such an unprecedented conclusion of the land.

You have your Conquerors, then you have your Rulers. An example to such a Ruler would be Princess Celestia, Princess Cadance, Thorax, etc. Notice how they have managed to maintain, protect and rule over their subjects, to ensure they are stable and have all the necessary daily needs they require to live a normal life. In media the Ruler trope can be seen in both ways as a 'Benevolent Ruler' or a Tyrant due to their personality or how the story portrays such a character. In this show we have seen both styles from the grace and beauty of the Princesses of Equestria and the Crystal Empire, to the Tyrannical dictatorship of Starlight Glimmer in Our Town. Now for Tyrants. Well, you've seen the before and how they have managed to try out their ways to take over the land of Equestria. Each one doing... Eh, a poor job at least. All except Sombra, who managed to Conquer the Crystal Empire and made it for himself, as well as maintaining control over such a large portion of territory for quite a long time before Twilight and her friends stopped him and overthrew his rule and dominance over the land. Was a good ruler? Heck no! He was a case of both a Conquering King and a Tyrant wrapped in a bow.
