Wolfe makes a point of many Earthly species being extinct by Sev's time, 
and eagles are endangered even today. There could be a similar shortage 
of the highest flying gesse, perhaps from Exultants overhunting them 
from flyers.

The increased vantage height of the towers should let the Wall be 
visible from *farther* away, rather than constraining the distance closer.
