Since the Red Star rose in the east, the people of Pern decided to
establish a holding in the eastern mountains, provided a suitable cavesite
could be found. Only solid rock and metal, both of which were in distressingly
short supply on Pern, were impervious to the burning score of Thread.
The winged, tailed, fire-breathing dragons had by then been bred to a
size that required more spacious accommodations than the cliffside holds could
provide. The cave-pocked cones of extinct volcanoes, one high above the first
Fort, the other in the Benden Mountains, proved to be adequate and required
only a few improvements to be made habitable. However, such projects took the
last of the fuel for the great stone-cutters, which had been programmed only
for regular mining operations, not for wholesale cliff excavations. Subsequent
holds and Weyrs had to be hand-hewn.
The dragons and their riders in their high places and the people in
their cave holds went about their separate tasks, and each developed habits
that became custom, which solidified into tradition as incontrovertible as
law. And when a Fall of Thread was imminent-when the Red Star was visible at
dawn through the Star Stones erected on the rim of each Weyr, the dragons and
their riders mobilized to protect the people of Pern.
Then came an interval of two hundred Turns of the planet Pern around its
primary, when the Red Star was at the far end of its erratic orbit, a frozen,
lonely captive. No Thread fell on Pern. The inhabitants erased the signs of
Thread depredation and grew crops, planted orchards and thought of
reforestation for the slopes denuded by Thread. They even managed to forget
that they had once been in great danger of extinction. Then, when the
wandering planet returned, the Threads fell again, bringing another fifty
years of attack from the skies. Once again the Pernese thanked their
ancestors, now many generations removed, for providing the dragons whose fiery
breath seared the falling Thread midair.
Dragonkind, too, had prospered during that Interval and had settled in
four other locations, following the master plan of interim defense.
Recollections of Earth receded further from Pernese memories with each
generation until knowledge of Mankind's origins degenerated into a myth. The
significance of the southern hemisphere, and the instructions formulated by
the colonial defenders of dragon and grub, became garbled and lost in the more
immediate struggle to survive.
By the Sixth Pass of the Red Star, a complicated
socio-political-economic structure had been developed to deal with the
recurrent evil. The six Weyrs, as the old volcanic habitations of the
dragonfolk were called, pledged themselves to protect Pern, each Weyr having a
geographical section of the Northern Continent literally under its wing. The
rest of the population agreed to tithe support to the Weyrs since the
dragonmen did not have arable land in their volcanic homes, could not afford
to take time away from nurturing their dragons to learn other trades during
peacetime, and could not take time away from protecting the planet during
Passes.
Settlements, called holds, developed wherever natural caves were
found-some, of course, more extensive or strategically placed than others. It
took a strong man to exercise control over terrified people during Thread
attacks; it took wise administration to conserve victuals when nothing could
be safely grown, and it took extraordinary measures to control population and
keep it productive and healthy until such time as the menace passed.
