Loud In The Trees

After Doomsday.

A song sung by a spaceman in Yotl's Nest tells the women of Terran Traders that other human beings are alive. Sigrid says that there can only be two such days in her life. Of course Donnan asks what is the other one:

"'V'en my first-born is laid in my arms.'

"For a while only the wind blew, loud in the trees." (14, p. 112)

This time the wind underlines what is important, loudly for emphasis. That wind gets everywhere. We can think of it as:

"...the wind at the edge of the world forever calling."

-see here.

It certainly blows between worlds. If enough works by Poul Anderson were to be filmed, then there could certainly be a compilation of scenes with wind punctuating dialogue and commenting on action in Ys, in Gothland and on other planets.
