As the colony ships approached Pern, Mar Dook made sure the scientists kept on track with their priorities, including placating and reproving Ted Tubberman. He was part of the first group to land on Pern and helped to choose the site for farming.
When Thread fell, he helped to study it. At one point, he suggested that Thread had been designed to harm humans. When the leadership of Pern held a public meeting to inform the people of their findings, Mar Dook was one of those on stage.
Mar Dook had a son, named Kes, who was trained in agronomy.
