Not everyone in the Isles is united behind you though. Rival families, also descended from Somerled, dispute your leadership. They believe they have as much right to hold power as you do. The MacDougalls of Lorn are particularly against you.
They have forged alliances with the Balliols and the Comyns, both of whom are enemies of Robert the Bruce. They cannot be trusted. They will go to any lengths to destroy you.
