And speaking about the Northern Kingdoms, are they any better? They just keep fighting each other, raping, pillaging villages on the way for some damn small region they have been fighting for hundreds of years.
At least when Nilfgaard takes the North, it will be somewhat stable."
Yeahh....right, and the bloody rebellions in the provinces (quelled in blood by the way and enormous atrocities of Gemmera's Pacificators) are a sign of imperial stability HAHAHA! Books my friend addressed that matter, Geralt (and Ciri) saw first hand how's life in imperial provinces, hint it's not pleasant. Just to add few words of mine hehe.
Speaking of empires, from many fictional empires there is one that I think would stomp Nilfgaard, surpass it in both it's successfulness and ruthlessness, wealth and military power (not to mention engineering knowledge) and i'm talking about....empire of Numenor, yeas guys I;m talking about Tolkien hahaha. Strangely enough numenoreans indeed had some claim to the incredibly arrogant view of superiority, they were enhanced humans of grat stature, strength and endurance, attractive look, mental powers and some other vague magic abilities, advanced culture that profited from teachings of Elves and their culture, and yet they became power hungry tyrants, that mercilessly opressed and enslaved people of Middle Earth, build colonial empire and robbed those lands of riches and resources on a massive scale, slaughtering thousands (while centuries before they were benevolent teachers of the crafts of civilization for natives) and in their latest period they not only institutionalized slavery but started to MAKE HUMAN SACRIFICES of people abducted from Middle Earth in their dark cult of Morgoth and the king Ar-Pharazon was the greatest tyrant ever known also with desire of total world domination hahaha (very much like Emhyr, even surprisingly Ar-Pharazon took sceptre by force, and Miriel his cousin for wife pretty much against her will, Emhyr had to regain throne from usurper and he also considered incestuous relationship for his goals, intriguing similarities hehehe, no wonder the Second Age is also called the Dark Years, from one side Sauron and his ever growing empire he rules as supreme God-King and the other utterly corrupt superpower of Numenor).
