Nightwings

It was Avluela the Flier's scarlet and ebony wings that led the Watcher to the seven hills of the ancient city, leaving the skies and deep space unguarded. And so the invaders came and conquered and Avluela became lost in the turmoil. "Only at night, on the winds of darkness, can she soar. And it was Avluela the Flier's ebony and scarlet wings that led the Watcher to the seven hills of the ancient city from which, in a moment of weakness, the Watcher failed his vigil, leaving the skies and deep space unguarded."--Back cover
