" Beware the man who loves battle. Ravn had told me that only one man in three or perhaps one man in four is a real warrior and the rest are reluctant fighters, but I was to learn that only one man in twenty is a lover of battle. Such men were the most dangerous, the most skillful, the ones who reaped the souls, and the ones to fear. "

― Bernard Cornwell , The Last Kingdom (The Saxon Stories, #1)
