Corazon Cervantes was a medic and agronomist on Pern during the First Pass. After landing she was in charge of tubers and squash.
Corazon, Basil Tomlinson, and Beth Eagles were sent from Fort Hold to deal with the people wounded during the Second Crossing. Dart made sure to tell them about Theo Force's injuries; in turn Theo told them about Jim Tillek's injuries.
