Wind In Beringia

The Shield Of Time.

Paleo-Indians from Siberia, led by Red Wolf, arrive in Beringia and confront the archaic Caucasoids, led by Wanda's friend, Aryut, whose ancestors had come from Asia earlier. 

"Red Wolf stopped three paces from [Aryut]. Eyes stared into eyes. Silence stretched amidst the wind." (p. 156)

Wind often underlines pregnant silences.

Wanda, now absent, had protected Aryut at his first encounter with Red Wolf but:

"'Where is your protector today?' Red Wolf jeered. Only the wind replied." (p. 157)

This means that there is no reply but often the wind comes across as an active participant. 

Poul Anderson's universes are haunted by winds. Anderson quotes Shelley in Trader To The Stars so here is some relevant Shelley:

O wild West Wind, thou breath of Autumn's being,

Thou, from whose unseen presence the leaves dead

Are driven, like ghosts from an enchanter fleeing,

-from here.
