SROs (short for “sentient robotic organisms”) are among
the most advanced forms of robots, with internal circuits
and positronic brains so complex that they, like androids, attract
a soul and develop true artificial intelligence and free will. SROs
are most common on Aballon, though they are different from
the native anacites. Unlike androids, SROs do not have a unified
appearance, and many are at best vaguely humanoid in shape,
while others have shapes designed purely to assist in their
primary functions.
In the Pact Worlds and many other regions, SROs have the
same legal protections as androids, but sadly the bias many
living creatures share against things that look similar to mindless
machines means those protections are less widespread, and less
respected, than for androids.
