Lifeworker

Lifeworkers were one of the main social classes in Forerunner society. They specialized in all living things and medicine, including experimenting with new forms of life. The highest possible rank achievable by a Lifeworker was Lifeshaper. Earth, then called "Erde-Tyrene", was at one point an experimental planet under the care of the Librarian, a Lifeshaper and one of the most powerful Lifeworkers to have ever lived. Bornstellar Makes Eternal Lasting encountered the Librarian on Earth during his tenure as a Miner.
