"Eert ... mn?"

I pointed at the sky, the incredible sky. "From out there. From another world."

It thought about that for a while. I waited. We already knew that the Zens had been better astronomers at their peak than we were right now, even though they'd never mastered space travel; so I didn't expect this one to boggle at the notion of creatures from another world. It didn't. Finally it nodded, and I thought, as I had often before, how curious it was that this gesture should be common to Earthmen and Zen.

"So. Eert-mn," it said. "And you know what I am?"

When I understood, I nodded, too. Then I said, "Yes," realizing that the nod wasn't visible through the one-way glass of my helmet.

"I am—last of Zen," it said.

I said nothing. I was studying it closely, looking for the features which Yurt had described to us: the lighter red fur of arms and neck, the peculiar formation of flesh and horn on the lower abdomen. They were there. From the coloring, I knew this Zen was a female.

The mouth worked again—not with emotion, I knew, but with the unfamiliar act of speaking. "I have been here for—for—" she hesitated—"I don't know. For five hundred of my years."

"For about three thousand of mine," I told her.
