Attack the Douglas estates and imprison or murder anyone who protests. You have your own safety to consider. You need nobles you can trust.
Arrange a meeting with the 8th Earl of Douglas. You want to see an end to all this feuding.
Which card will you play?
Arrange a meeting with the Lords of the Isles and bribe them into double-crossing the 'Black' Douglases. This will strengthen the Crown's relations in the west and get rid of the Douglas threat to your ambitions.
