What if it was Orsinium that turned the tide of war and conquered the Empire? That would be something else. Something I'd like to see. An Orcish Emperor. I still dont see it happening.
I'd like to think that a foreign advisory would come to the aid of the Empire as well. You know like those Potentates. Something tells me that it will happen.
Alcohol has never forced anyone to do anything. Add a little alcohol, some girls and guys on the right day of the year all around the province for 30 years. Nothing to it. Not much manpower needed, the khajiit will have other babies too, nothing will be suspected. Nothing will be found out. Just placing dominos, and letting them fall over naturally.
Dude these are Khajiit, they aren't dumb mindless beasts. They are cunning and intellectual. A plan like that would be diffused at best, and it would tell the people of Elsweyr what the Dominion was really up to. War-Mongering. If by my understanding the Khajiit are a peaceful race. Only prone to violence when necessity calls for it.
