Auch's older brother, the prince, had forced several women from town to be his concubines. Determined to reproach his brother for his unseemly behavior, Auch stormed down the halls of the castle. The poisoned arrow missed him by a hair's breadth, piercing one of the manservants nearby. One of his brother's subordinates had fired the shaft. Enraged, Auch slew the aggressor and ran straight to his brother's quarters. Without batting an eyelash, he sank his sword into the prince's chest.
