The Arrival at Pern
The ship 'Bahrain' lands on Pern, carrying over 6,000 colonists from Earth-allied planets. Admiral Paul Benden and Governor Emily Boll lead a diverse group of scientists, engineers, and farmers, all eager to build a self-sufficient colony. Early surveys show a beautiful world with two suns, Rukbat and its companion, and many plants and animals, including small, telepathic, fire-lizard-like creatures. The colonists start their main settlement, Landing, setting up farms and research posts. Everyone is excited, admiring Pern's beauty and apparent safety, unaware of the coming disaster that will soon threaten them.
The First Threads
Years into the colonization, the Red Star, a new celestial body, moves close to Pern. At first, its appearance is just a scientific curiosity, but then strange, silvery strands begin to fall from the sky. These 'Threads' are quickly identified as destructive, extraterrestrial spores that consume all organic matter—plants, animals, and even humans—leaving only sterile ash. The colonists are completely surprised. Their advanced technology does not work against the rapidly multiplying menace. Panic spreads as they realize the Red Star is on a cycle, bringing a devastating rain of Thread every 200 years, threatening to destroy all life on Pern.
Desperate Measures and the Fire-Lizards
As Thread destroys crops and buildings, the colonists' morale drops. They try various defenses, from flamethrowers to chemicals, but nothing offers a lasting solution against the constant attack. During this time, scientist Kitti Ping observes the native fire-lizards, small, winged reptiles. She notices their unusual abilities: they can breathe a phosphine-based flame to burn Thread, and they can also teleport short distances, 'blinking' out of danger. This discovery gives the scientific community, especially F'nor and his team, a new idea: these creatures might be the key to their survival.
The Genetic Project: Creating Dragons
Seeing the fire-lizards' potential, Kitti Ping suggests a radical genetic engineering project: to breed and enhance fire-lizards, making them larger, smarter, and more telepathic, so humans can ride them. This controversial plan faces ethical and practical problems, but the severe threat of Thread outweighs most objections. Kitti, with support from Paul Benden and Emily Boll, begins her careful work, selecting fire-lizard eggs and embryos, manipulating their genetic code to speed up growth and increase desired traits. The goal is to create a partner for humans, a creature large enough to carry a rider, smart enough to communicate, and able to fight Thread from the sky.
The First Dragonets
After much research, the first modified fire-lizard eggs hatch. These 'dragonets' are larger than their wild ancestors but still too small for human riders. However, they show increased intelligence, stronger telepathic bonds with their handlers, and a more powerful flame. These early successes confirm Kitti Ping's theories and boost the colonists' hopes. The dragonets are trained to hunt Thread, proving effective even at their smaller size. The experience gained from working with these first generations provides important data for Kitti's ongoing genetic work, guiding her toward creating full-sized, rideable dragons.
The Birth of the First Dragon
Years of genetic work result in the hatching of the first truly large, rideable dragon. This important event happens inside the Weyr, a cavern system built to house the growing dragon population. A young colonist named F'lar, who has been involved in the dragon project, is present at the hatching. As the golden dragonet comes out of its shell, it 'impresses' upon F'lar, forming a telepathic bond that will last their lifetimes. This impression shows that Kitti Ping's vision has been achieved and that humans and dragons can form the partnership needed to fight Thread.
Training the Dragonriders
With the successful hatching and impression of the first dragons, the focus moves to training the dragonriders. A strict program is set up, covering not only the physical demands of riding and fighting Thread in the air but also the telepathic communication and understanding between rider and dragon. Paul Benden, now a key figure in the dragon project, oversees the military aspects, while Kitti Ping continues to monitor the dragons' health and genetic stability. The training is intense and dangerous, as riders learn to coordinate attacks, using their dragons' flame and teleportation to destroy Thread before it reaches the ground. This is the start of the Dragonriders of Pern.
The First Pass of the Red Star
The Red Star makes its closest approach, unleashing a massive, sustained Threadfall across Pern. This is the ultimate test for the new Dragonriders. Led by F'lar and his golden dragon, Fanth, the dragons fly into the sky, fighting Thread in aerial combat. The battle is brutal and costly, with dragons and riders getting hurt and some dying. However, their combined efforts are effective. The dragons' flame and their ability to 'blink' through space allow them to intercept and burn large amounts of Thread, protecting the settlements and farms that would have been destroyed. The first major Threadfall is successfully repelled, though with significant loss, confirming the dragons' role as Pern's saviors.
Establishing the Weyrs
After the first major Threadfall, the colonists realize they need dedicated, secure bases for the growing dragon population and their riders. The natural cavern systems, first used for dragon hatching, are expanded and strengthened, becoming the first Weyrs. These Weyrs are designed to be self-sufficient communities, providing living quarters, training facilities, and secure areas for dragon eggs. They become the main centers for dragonrider culture and defense. Establishing the Weyrs organizes Pern's defense, ensuring that future generations of dragons and riders will have the resources needed to continue their fight against Thread.
The Legacy of the First Pass
The first Pass of the Red Star changes Pernese society. The dragons, once a desperate scientific experiment, are now essential for survival. The colonists, now 'Pernese,' begin to adapt their lives around the cyclical threat of Thread and the Dragonriders. Farming shifts to more resistant crops, settlements are fortified, and the importance of the Weyrs and their riders is supreme. The initial, technologically advanced society gradually relies more on the symbiotic relationship with their dragons, setting the stage for the future feudal-like society seen in later Pern books, where the Weyrs hold ultimate authority in the planet's defense.
