Arnor and Swordfell were already allied, and Morek and Arnor were already allied. It was already headed in that direction and would have gone that way with or without my !@#$ing help. Don't be so !@#$ing dense. I'm on IRC if you want to talk about it.
Swordfell was allied to HD as well until you wrecked that. In fact Swordfell hated Morek. There was a lot of animosity there until the two rulers actually started chatting and worked out their differences.
