Brellick was a servant and laboratory assistant of the Astronomer. He lived in Dayport and worked in the Astronomer's Workshop. The Astronomer was attempting to leave The City and reach an unknown planet he had discovered, and Brellick served as his first test pilot. Unfortunately, the first test flight was a disaster, and Brellick was killed, his remains landing on the great statue in the plaza. The astronomer attributed this tragedy to his having forgotten to add a protective layer of lead on the bottom of the box.
After Brellick's death, the astronomer hired Hilde to serve as the second test pilot.
