"He was poisoned, and Mejnour fled." "Mejnour fled not," answered the stranger, quickly and proudly. "Mejnour could not fly from danger, for to him danger is a thing long left behind. It was the day before the duke took the fatal draught which he believed was to confer on the mortal the immortal boon that, finding my power over him was gone, I abandoned him to his doom.

But a truce with this: I loved your grandsire; I would save the last of his race. Oppose not thyself to Zicci. Oppose not thyself to thine evil passions. Draw back from the precipice while there is yet time. In thy front and in thine eyes I detect some of that diviner glory which belonged to thy race.
