Faber-of-Will-and-Might

Faber, more commonly known by his title as the Master Builder, was an immensely powerful Forerunner Builder. He commissioned the construction of the Halo Array, and co-created Mendicant Bias alongside the Didact.

Biography
Faber was given the title of Master Builder around 100,312 B.C.E. As a last-resort defensive measure against the Flood, and as a way to secure the preeminence of the Builder rate, he commissioned the creation of an array of weapons capable of purging all sentient life from a star system - and, if the situation became dire, the entire galaxy. Despite opposition from the Didact and the Prometheans, the Forerunner Council agreed to Faber's proposal, causing the Didact to go into exile. Under his orders, the father of Bornstellar Makes Eternal Lasting designed the Halo Array, and twelve of the weapons were built by his guild.

During the Forerunner-Flood War, he arrived at Janjur Qom in search of one of the Halo Installations, which had been assigned to Mendicant Bias and had gone missing when the AI went rampant. There, he met with Bornstellar and the Didact, who had come to meet with the San'Shyuum leadership. He placed the Didact under arrest and sent Bornstellar back to his family. When the Didact later refused to give vital information to the Master Builder, he executed him. The Didact would live on, however, as his memories and personality had been transferred to Bornstellar's mind. Their arrival, following the Librarian's indexing of the San'Shyuum, caused the San'Shyuum to rebel against the Forerunners. In retaliation, the Master Builder used a Halo sterilize the San'Shyuum population.

However, the Master Builder had exceeded his authority, and many of his closest allies felt he had gone too far. The Builders stripped Faber of his title, and he was put on trial before the Forerunner council for the unsanctioned use of a Halo and other war crimes. However, the trial was interrupted by Mendicant Bias' assault on the Capital.
