Fifth head times 2 brothers

I agree with Tony that the existine Annese race was an offshoot of the human race (or vice versa) at one time. In addition to the direct clues, which have been mentioned several times, I also think it is stated metaphorically, in the middle novella. The two brothers (Eastwind and Sandwalker) were separated at birth, and came together later. They were convinced that they would switch bodies, then one was killed, leaving the remaining uncertain which one he had been originally. While this does not strike me as plausible in the story (there should be too many physical clues as to which he was), it is a good metaphor for the two races. That they were brothers, long separated, indicates another piece of evidence that the two races came from the same source, though long since separated. One of the brothers dying off and the other being uncertain of identity echoes the same issues with respect to the two races. So, in addition to the clues presented over and over again, I think the metaphor indicates also that the reader was meant to think of the two races as linked. When in time the migration should be placed, however, is not clear to me. Neal Smith
