Degar, the Rouser of the Third Blade: "Even the mightiest warrior might falter in combat. War is terrifying, and the Watchers are more terrible than any other foe. To combat fear, the rousers exist. They are a caste of seer that can see into the hearts of soldiers and whisper just the right words of encouragement. In the darkest of times, they sing tales of glorious victories of the past. Every blade has one - a hundred in the whole legion - and without one, a blade is as good as lost."
