Occasional chapters of "Dragonsblood" are set soon after the end of the First Pass of the Red Star, nearly 450 years before most of the action. There (or "then") the elderly Wind Blossom, a geneticist and daughter of the legendary Kitti Ping, is bemoaning the gradual loss of manufactured items and the technology to create them. She and her ex-protégé Tieran are startled by two fire-lizards who literally fall from the sky. One, a gold, dies upon arrival. They nurse the other one, a bronze, back to health, using the last of the antibiotics. Not knowing if the fire-lizard's sickness is contagious, they quarantine it until it recovers. Tieran adopts the fire lizard and names him Grenn – the name found on the harness he was wearing. Further investigation of the decorations on Grenn's harness leads to the incredible conclusion that he is from the future. Since fire-lizards provided the genetic basis that Kitti Ping used to build the Thread-fighting dragons (and Wind Blossom used to build the watch-whers), they speculate that this future affliction of fire-lizards might be fatal to dragons, and that is confirmed when a dead gold dragonet appears – one obviously sickened by the same future disease. The dragon's body is destroyed, but Tieran recovers a decorated piece of metal from its harness.
