Actually, COMS wasn't around until recently and, matter of fact, you killed millions of natives with diseases while Qarir had to give them medicine for the diseases.
Medicines they wouldn't have. The only ones who didn't infect the natives were the Israelites (we settled in a nasty swamp) and the men of Rhun who settled in the everglades
False, the man of moscovy drunk enough alcohol that their level of alcohol in their blood is high enough to kill any disease (If griss can use unreal gliders we can use alcohol to kill most of the diseases)
