Saurithons
Saurithons are a fictional species featured in the "Dragonriders of Pern" series by Anne McCaffrey. They are a type of dragon that hatches from eggs and bonds telepathically with a human rider. Unlike the smaller, more common dragons, Saurithons are immense in size, with wingspans that can reach hundreds of feet. Their primary role in Pernese society is to protect the planet from Thread, a deadly airborne organism that falls from the sky. Saurithons are capable of consuming Thread, thus preventing it from reaching the ground and destroying crops and settlements. They possess telepathic abilities that allow them to communicate with their riders and with other dragons, forming a complex network of awareness and cooperation. Saurithons are depicted as intelligent and fiercely loyal creatures, living for centuries and passing on knowledge and memories through the Impressing process. Their lifespans are significantly longer than those of humans, allowing for a deep and enduring partnership between dragon and rider. The bond is so strong that if a rider dies, their dragon often dies of grief shortly thereafter. Saurithons are a vital part of the Pernese ecosystem and culture, essential for the survival of humanity on the planet.
