This passage introduces another alien aspect of this world that is left unexplained until later. The book presents a universe that is entirely strange yet vivid, and it seems visceral and real. The woman at the beginning of the book was described as a “stone eater,” and the way the figure eats the crystals suggest that he might be a stone eater as well. At the same time, he seems to be learning how to be human. The figure also has great patience and a different sense of time than human beings, as it moves at the pace of days rather than hours or minutes.
