The Woman in White suggests that urban diversity and cultural exchange drive cities’ births—and so are responsible for the deaths of neighboring realities and all their inhabitants. This odd piece of world-building casts diversity in a negative light. Since the Woman in White has invoked Lovecraft, we might expect her to be lying or confused—but Bronca, who has no reason to lie, also believes that diverse urban areas, in creating great cities, give rise to mass death. It is not clear whether the novel intends this part of its mythology to allegorize the environmental costs of large cities. The revelation that Aislyn once taught herself Gaelic but forgot it for lack of conversational partners both suggests that her xenophobia is limited to non-white foreigners—she’s fine with foreign languages spoken by white people—and reminds the reader of her social isolation. Finally, in claiming not to judge humanity’s “nature,” the Woman suggests that human beings cannot help but build cities that destroy neighboring realities. By implication, this urban destruction is in human “nature,” so humanity must be destroyed to be stopped. The Woman’s invocation may remind the reader of the Woman’s conversation with Bronca, in which Bronca denied the existence of fixed human nature—which hints that perhaps humanity’s cities need not be so destructive.
