Lifeworker (Earth-5875)

Lifeworkers were one of the rates in forerunner society, specializing in everything relating to living things, from plant, to animals, as well as medicine. They were rated below Builders, but above Warrior-Servants. The Librarian was the most prominent known Lifeworker, known as the Lifeshaper.

Lifeworkers were the creators of the ecosystems of the Halo Array and Ark, and devised the Conservation Measure during the Forerunner-Xenomorph War, in order to index the remaining sapient species of the galaxy aboard the Ark to survive the activation of the Halos.
