“ Richard rubbed his temples. He had a headache from lack of sleep. Don't you understand? This isn't about conquering lands and taking things from others; this is about fighting oppression.The general rested a boot on the gilded rung of a chair and hooked a thumb behind his wide belt. I don't see much difference. From my experience, the Master Rahl always thinks he knows best, and always wants to rule the world. You are your father's son. War is war. Reasons make no difference to us; we fight because we are told to, same as those on the other side. Reasons mean little to a man swinging his sword, trying to keep his head. ”
