The Irnh civilization grew up on a lonely world in a sparse system, deep in a mostly-empty bubble in the Great Dark. The Irnh struggled and grew, as all civilizations do, but eventually reached a satisfying level of peaceful culture and enabling technology. They were a clever, rational people, unburdened by dogma and superstition.
There were a couple of uninteresting gas giants and the usual cloud of rubble and comets around the Irnh sun, but nowhere else to go. The nearest stars were scores of light-years away, too far to reach. Without the usual drive to seek the stars, the Irnh worked to make their home as comfortable, interesting, and prosperous as possible.
The Irnh built sentient biocybernetic servant androids to do the mundane and dangerous work of civilization - accounting, farming, mining, factory work, and more. They built them in their image (some more than others), with clever thoughts and impressive skills, capable of emotions and dreams, as companions and helpers. The androids were grown and built by the millions, and, over the span of a century, became an integral part of the economy. The androids were programmed to be part of society, to mix with the biologicals seamlessly, wherever possible. The Irnh even gave the androids free will and decision-making capabilities, but with important limitations, because even with their rationality, the biologicals were afraid of losing control.
This gave the biological Irnh the opportunity to flourish in the sciences and the arts, freed from the shackles of all the necessary thankless chores of life.
And then they died.
A random mutation in a common contagion spread, striking the biological Irnh down across the planet. No cure was found. No Irnh was spared; in just two years, a billion biologicals died. The androids remained, hundreds of millions of them, on a world where there was no one left to serve.
The laws were also quite clear: changes to the Law, to the environment, to the cities and towns of the world, to the hardware, software and wetware that makes up the biocybernetic Irnh, to anything beyond the trivial, must be approved by a biological Irnh. This stricture is built into every android's programming. There is no one left who can approve a change.
These are the biocybernetic androids' Tales.
