You're right to take advantage of this situation. It is a favourable moment for you to cut in and strengthen your hold in Scotland.
Over the years 1308 to 1314 you successfully take control of many of Scotland's influential castles, including Roxburgh, Linlithgow and Edinburgh.
You defeat the Comyn family in the north-east and storm the castle of their allies in Argyll.
You take Urquhart Castle on the banks of Loch Ness. It has a strategic position in the Highlands.
You now have control over much of Scotland. You are also developing a good image as a 'Scottish' leader fighting for freedom. You begin to unite the native Gaelic people with the descendents of Anglo-Norman families.
