Oar, the narrator of this story, first appeared in the novel Expendable. At the end of that book, she was left for dead after she grabbed an enemy and plunged with him from a window on the eightieth floor of a building.
To human eyes, Oar is as clear and transparent as glass. Although she actually has bones, muscles, and an assortment of internal organs, these were bioengineered to be indiscernible when humans look through her skin.
Oar’s ancestors were humans themselves, born on Earth around 2000 B.C. At that time, a collection of Homo sapiens were removed by aliens to the planet Melaquin, where the aliens gave these people a new home. The aliens didn’t explain why they did this, but they built the humans beautiful glass cities with self-repairing robotic systems designed to provide all the comforts of life.
The aliens gave these humans one additional gift: the people’s children were born as strong, intelligent glasslike humanoids who never grew old or sick, and who were tough enough to withstand damage that would kill normal flesh and blood. Only later did it become apparent that these glass offspring had a flaw: although their bodies could survive for millennia, their minds were not so long-lasting. Around the age of fifty, these people succumbed to so-called "Tired Brains" — they lost interest in all aspects of existence, often just lying down and never bothering to get up again. They could still stir themselves if something remarkable happened, but for the most part, they remained catatonic down through the centuries.
Glass parents continued to have glass children, but in decreasing numbers. The population declined in cities, towns, and villages all over Melaquin — gradual extinction from pure ennui. By the time of the events in Expendable (the Earth year 2452 A.D.), almost the entire species had fallen into apathetic hibernation. Only a few were still young enough to have active brains.
In Expendable, Oar was forty-five… on the verge of her race’s customary "senility."
Now she’s four years older.
