 Choose the most likely outcome if the narrator was not determined to be Yandro?
He was Yandro, the Stranger of the Prophecy—and he found that he was destined to fight both sides. Words formed themselves on my thick tongue, words that must have been spoken by so many reviving unfortunates through the ages: "Where am I?" The voice was telling me that I had been snatched from worlds away, for a specified purpose here on whatever windswept planet Dondromogon might be. "I am a scientist," offered Doriza, and came forward. "Surely you are Yandro, the Conquering Stranger," he said, intoning as if in formal prayer. If indeed he is Yandro," and he was most respectful, "he will appreciate, like a good military mind, my caution against possible impostors."
 He would not be honored on Dondromogon.
 He would have never met Doriza.  He would be sent back to Earth.  He would not be honored on Dondromogon.  His memory would have came back faster.
