98,445 BCE

• The Forerunner Prometheans, opposed to the construction of the Halo Array, lose their political battle against an extreme faction of the Builders and are forced out of the Council, with most going into into exile in a Cryptum or executed. Shortly afterward, the Deep Reverence is retired near Janjur Qom. For the next thousand years, the Council continues to marginalize and diminish the role of the entire Warrior-Servant rate while twelve Halo rings are constructed by the guild of Bornstellar's father under orders of the Master Builder Faber.
• Trial decides to become a Lifeworker instead of a Builder. Her family rejected her as a result, and she was adopted by a foster family.
