L'rat was wingleader of the second wing at Telgar Weyr at the end of the Second Interval. He was concerned about the holds being unable to communicate with the weyr in the abscence of fire-lizards. He also believed that the Weyr should communicate with the other Weyrs about the disease, when it first appeared. He was one of the former Igen dragonriders who had joined Telgar when Igen was abandoned.
