Faber-of-Will-and-Might

Faber-of-Will-and-Might, most commonly known by his title as the Master Builder, was an immensely powerful but exceedingly corrupt member of the Isu Builder rate. A ruthless politician and cunning manipulator, he commissioned the construction of the Halo Array and was the Ur-Didact's political arch-enemy for many millennia due to the latter's adamant opposition to the Halos. This conflict eventually culminated in Faber's takeover of the Old Council and the Didact's exile.
