So, this novel was absurdly huge, straight up finishing over break was more important than annotating at the time, unfortunately, but here it goes.
In general, race in Cyteen seemed to be of absolutely minimal importance. Surface physical differences deteriorated (or evolved) into genetic ones: the most blatant division within Resuene society is the dichotomy of CIT and azi. However, I find myself wondering if that division is not just a displacement of race issues. The azi certainly seem to be the inferior members of this hierarchical structure. Although they have an important function within the society and do not seem to mind their lower status, they are forced to be servants of the upper strata of CIT's.
