"Yes," I said simply, "sometime I would like to see the Scanning Room."
"But much of our knowledge comes from our implants," said Misk. "We implant humans with a control web and transmitting device. The lenses of their eyes are altered in such a way that what they see is registered by means of transducers on scent-screens in the scanning room. We can also speak and act by means of them, when the control web is activated in the Sardar."
"The eyes look different?" I asked.
"Sometimes not," said Misk, "sometimes yes."
"Was the creature Parp so implanted?" I asked, remembering his eyes.
"Yes," said Misk, "as was the man from Ar whom you met on the road long ago near Ko-ro-ba."
"But he threw off the control web," I said, "and spoke as he wished."
"Perhaps the webbing was faulty," said Misk.
"But if it was not?" I asked.
"Then he was most remarkable," said Misk. "Most remarkable."
