hey built a city
on the surface and protected it with the magnetic force screen.

By the time the Satorians found the city, it was too late. A battle
fleet was mobilized and rushed to the spot, but the city was
impregnable. The great domed power stations were already in operation,
and they were made of nonmagnetic materials, so they could not be pulled
from the ground. The magnetic beams were neutralized by the shield, and
no ship could pass through it without killing every man aboard.

That first city was a giant munitions plant. The Nansalians built
factories there and laughed while the armies of Sator raged impotently
at the magnetic barrier. They tried sending missiles through, but the
induction heating in every metal part of the bombs either caused them to
explode instantly or to drop harmlessly and burn.

In the meantime, the men of Nansal were building their fleet. The
Satorians stepped up production, too, but the Nansalians had developed a
method of projecting the magnetic screen. Any approaching Satorian ship
had its magnetic support cut from under it, and it crashed to the
ground.

It took nearly thirty years of hard work and harder fighting for the
Nansalians to convince the people of Sator that Nansal and the
philosophy of Norus had not only not been wiped out, but was capable of
wiping out the Satorians.

With their screened and protected fleet, the followers of Norus smashed
the Satorian cities, and drove their enemy back to Sator.

There were only three enemy cities left on Nansal when, somehow, they
managed to learn the secret of the magnetic screen.

By this time, the forces of Nansal had increased tremendously, and they
developed the next surprise for the Satorians. One after another, the
three remaining cities were destroyed by a barrage of poison gas.

The fleet of Sator tried to retaliate, but the Nansalians were prepared
for them. Every building had been sealed and filters had been built into
the air conditioning systems.

Shortly, the men of Nansal were again in control of their planet, and
the fleet stood guard over the planet.

The Satorians, beaten technologically, were still not ready to give up.
Falling back on their peculiar philosophy of life, they pulled a trick
the Nansalians would never have thought of. They sued for peace.

The government of Nansal was willing; they had had enough of bloodshed.
They permitted a delegation to arrive. The ship was escorted into the
city and t
