The Progenitor Council is a group of high ranking noble vampires from rank sixth to first that are tasked in monitoring the lower rank vampires and it is only these vampires that are able to attend the Council. The Council is led by Urd Geales, a second and the current strongest progenitor. There are a total of 19 vampires (excluding the First Progenitor Sika Madu and former 2nd Progenitor Saito).
The Progenitor Council's goal is to annihilate the Demon Army and to destroy any organization that conducts Human Experimentation. They conduct meetings every once in a while to make discuss and decide on important issues like the Human Experimentation or The Demon Army issues. The meeting can also be conducted in emergencies, as Ferid Bathory, a low ranking vampire, conducted the meeting when the humans invaded Sanguinem.
The council meetings are held in their own castles where they contact each other through a video call. The Progenitors only meet in person if they are punishing vampires or dealing with something important.
