Yes, you are right Karamis, the invasion of Coriona was bloodless. I ask you this though: would you stand for hostile strangers coming into your house, making camp there, and forcibly taking all your possessions and basically ruining your life? I doubt it. Parrius was given many chances and many warnings. They chose to ignore them all and continue on with the little invasion they had. I happen to know that they also planned on taking other villages after that until they had enough gold to start invading cities. Consider the actions of Mercinae and Thakria simply nipping in the bud what could have been world-wide bloodshed.
