I'm wondering if the resistance member that General Aldynn killed was a disguised corpse brigade member. I imagine that they might want to have control over how Ala Mhigo is governed. Most likely so that they can create another mad king, or just mess with the people of Ala Gryrria. They have to be having a big role in it since they are becoming more active according to the various NPCs and the leader of Little Ala Mhigo.
