F'lar and Lessa were vindicated when the deadly Thread returned as the records predicted and Lessa used her discovery that dragons could move between time to go back four hundred years and persuade the dragonriders of the past to come to her time. F'lar was mostly relieved to have someone experienced at fighting Thread step forward and help with the crisis, but the solution came with a lot of new problems. A few months later and the disagreements between the "Oldtimer" dragonriders and civilian holders are growing, and F'lar himself is losing patience with their arrogance. This means that for the first time ever, dragonriders are threatening to use the dragons as weapons against civilians, and the Lords Holder of Pern are looking to F'lar for another miracle.
