What unusual qualities does Nunez notice about the village's houses?

When Nunez descends into the valley, he stumbles across a strange little village. He's never seen anything quite like this place before. For one thing, all the houses look like they've been built by blind people. There's a good reason for that: they were. For Nunez has entered into the fabled Country of the Blind, a place where no one has the power of sight.
As he walks through the streets of this unusual place, with its windowless houses, all bordered with curbs, he reflects on the old adage that in the land of the blind the one-eyed man is king. He thinks that the locals' blindness puts him in a position of power that will allow him to rule over this legendary corner of the globe. But in this particular case there are none so blind as those who can see, and Nunez soon discovers that the power of sight avails him nothing in a country where the locals have become use to having only four senses.
