Lord Renyard had a taste, it emerged, for abstraction. He reminded me a bit of my dad, who was always inclined to wander off the practical point into speculation. I began to lose the thread of the fox’s arguments and was glad whenever he paused to point out a spectacular view or describe some flora or fauna of the surrounding world.

  I was beginning to get tired and hungry by the time the tottering towers of the City in the Autumn Stars came in sight: a sprawl of tall tenements and chimneys, spires and domes. High overhead I could see pale, bright spots of faded color, rusty reds and dark yellows, which might indeed have been ancient stars.

I couldn’t make out their features until they rode quite close. I would have called to them if I hadn’t remembered Lord Renyard’s instructions. When I saw their faces, I was glad I hadn’t It was the mysterious visitor and the other
