Central antagonist
The premise as retold across lore coverage rather than stated in a single citable official document. Proper names reported only through fan retellings are deliberately omitted here until they can be checked.
Brencis is described as far older than the valley he rules — a noble of the Roman world who climbed to high office, lost everything, and kept the appetite for power that got him there.
His hold on Vale Sangora begins with the plague. With the ruler of the day ordering the infected killed, Brencis offered the valley an alternative: a cure carried in his own blood, and relief from the ordinary burdens of tax and obligation.
The price was a blood tax — a few drops from every adult, taken at a gathering held each month. Those who could not survive the taking were, by the terms of the bargain, no longer obliged to anything. It is a protection racket dressed as salvation, and it is the order Coen is trying to break.
Listed rather than guessed. These promote out only against the retail build.
