“The forces of Caelin are led by General Eagler. He’s an honest man who has always treated us well. A good general. He must be aware of Lundgren’s evil plans to seize control of Caelin. I can only believe Lundgren’s holding someone dear to him as hostage. It’s so sad, but there’s nothing anyone can do. Why must so many innocents get hurt in the foolish games of nobles?”
The house on Chapter 9 also suggests that Eagler was threatened with a hostage. Again it’s not a direct statement from the man himself but with these 2 sources combined it’s about as clear-cut as a prime piece of mutton.
