Hire a henchman to go to Edward II's chambers and murder him. It won't be long before he looks to the north.
Such a peaceful solution would be nice. But you are forgetting the aim of
your mission. You are to carve out an independent future for Scotland. You
wish no alliance with the enemy!
With Edward II's withdrawal, you should make the most of this opportunity. There is plenty of land still to cover.
Which card will you play?
