Lifeworkers are mentioned a lot in the CEA terminals, who are these “Lifeworkers”??? I know that they were described in Halo:Cryptum but I didn’t read it yet so who are they???
this is quoted from halopedia:
The Lifeworkers were the third-highest rate in Forerunner society. They specialized in biology and medicine, especially with the experimentation of various forms of life. It was not uncommon for Lifeworkers to receive their own planets for experimentation. The highest possible rank achievable by a Lifeworker was Lifeshaper.
Read Cryptum. Then you will understand a lot more about the Forerunners and possible theories for Halo 4.
Lifeworkers were Forerunners. basically doctors and scientists. they were experts in all living things and medicine and stuff. the Librarian was a Lifeworker
