In the books
In Secrets of the Dragon Sanctuary, Trask mentions that he and Mara have been on a mission to Soaring Cliffs. The mission took place between the events in Grip of the Shadow Plague and Secrets of the Dragon Sanctuary. During the mission Trask and Mara interviewed a pair of adolescent dragons.
In Dragonwatch, Bracken is sent to defend Soaring Cliffs from dragons trying to overthrow the sanctuary. One reason Bracken goes is because Ronodin has been spotted inside the walls. At the end of Dragonwatch, news is delivered that Soaring Cliffs has fallen.
