Friend Gorrick was a Mechanist and expert in the construction of complex devices, such as the Builder's Children and Watchers. He wrote a concise study on the comparative power ingestion rates of immobile security units. Eventually Friend Gorrick was sent to work in the Mechanist base below Markham's Isle.
When Lotus infiltrated Markham's Isle, he damaged one of the Builder's children. Friend Pendelus brought it to the workshop and requested that Gorrick repair it. (T2: "Precious Cargo").
