r eyes shaded to ward off the Sickness.

But even at fourteen Mryna had outgrown charms and she didn't believe in
the Sickness. She had once asked the Earth-god what sickness meant, and
the screen in the answer house had given her a very detailed answer.
Mryna knew that none of the hundred girls and thirty boys inhabiting
Rythar had ever been sick. That, like the taboo of the Old Village, she
considered a childish superstition.

The Old Village wasn't large--three parallel roads, a mile long, lined
with the charred ruins of prefabs, which were exactly like the cottages
where the kids lived. It was nothing to inspire either fear or legend.
The village had burned a long time ago; the grass from the forest had
grown a green mantle over the skeletal walls.

For weeks Mryna poked through the ruins before she found anything of
significance--a few, scorched pages of a printed pamphlet buried deep in
the black earth. The paper excited her tremendously. It was different
from the film books photographed in the answer house. She had never
touched anything like it; and it seemed wonderful stuff.

She read the pamphlet eagerly. It was part of a promotional
advertisement of a world called Rythar, "the jewel of the Sirian Solar
System."

The description made it obvious that Rythar was the green paradise where
Mryna lived--the place she had been taught to call Earth. And the
pamphlet had been addressed to "Earthmen everywhere."

Mryna made her second find when she was fifteen, a textbook in
astronomy. For the first time in her life she read about the spinning
dust of the universe lying beyond the eternal rain mist that hid her
world.

The solid, stable Earth of her childhood was solid and stable no longer,
but a sphere turning through a black void. Nor was it properly called
Earth, but a planet named Rythar. The adjustment Mryna had to make was
shattering; she lost faith in everything she believed.

Yet the clock-work logic of astronomy appealed to her orderly mind. It
explained why the rain mist glowed with light during the day and turned
dark at night. Mryna had never seen a clear sky. She had no visual data
to tie her new concept to.

For six years she kept the secret. She hid the papers and the astronomy
text which she found in the Old Village. Later, after the metal men
came, she destroyed everything so none of the other women would know the
Earth-god was a man.

At first she kept the secret because she was afraid. F
