Master Builder

Master Builder was the highest rank attainable by a Forerunner Builder, the second most powerful in Forerunner society in terms of intelligence, wealth and political power only behind the first councilor. The rank could be revoked by the Council and a Master Builder could be brought to trial by a Supreme Mantle Court, formed by the Council. Faber was the last known Forerunner to hold the title around 100,000 B.C.E. ==List of appearances==*Halo: Cryptum ==Sources==
