"Dark Orbit" takes place in the same universe as some of Gilman's other work. In discussion, we noted that is a distinctly Leguinean universe--humanity colonized many planets so long ago we've forgot about them, humanity somewhat separated into different tribes as a result (doesn't seem like a species-level change as in Le Guin), there's instantaneous communication. In "Dark Orbit", a group of researchers is exploring a planet with many dark-matter related anomalies when they discover a settlement of blind humans living underground, whose different perception of reality may have granted them some unusual abilities. Possible spoilers below!
