here that Daniel Holm identified with an extraterrestrial tradition, I thought even as I wrote it that I was overstating the case although I was not sure how to rephrase it. Holm, a human being, wants his planet, Avalon, to remain in the Domain of Ythri. To this end, he confers with an Ythrian just returned from Ythri about how to resist encroachments by the human-led Terran Empire. However, this is a matter of present political arrangements, not of any tradition.
But then I reread the account of Ferune of Mistwood's funeral (see here) and Holm's response to it:
"'And that Terran thought we'd surrender.'"
-Poul Anderson, Rise Of The Terran Empire (New York, 2011), p. 560.
Here, Daniel Holm, who resisted his son joining a choth, draws strength from a rite of the two thousand years old Ythrian New Faith and says "'...we...'" All the barriers between himself and the Ythrians are down as he sets himself against those inspired by the Roman Empire.
Holm's other source of inspiration is the Terrestrial literature quoted by his deceased friend, Ferune of Mistwood:
"'...-their finest hour-...'" (p. 567)
Cultural fusion could not be completer.
