Five Great Nobles

Five Great Nobles (五大貴族) were a group of noble families that once had great influence in the Baharuth Empire.

Background
The Five Great Nobles were once prominent members of nobility in the Empire who were once the pillars of the Empire. However their end came when one of their own, the mother of Jircniv Rune Farlord El Nix was accused of assassinating the Emperor. For the crime Jircniv's mother's family was eradicated. Soon after Jircniv's brothers were killed one by one, followed by his mother. A power struggle ensued, where several aristocrats along with the Great Nobles were cut down by the Prince Jircniv. Those Great Nobles with private armies were ordered to send them against the Re-Estize Kingdom and had all those upkeep fees squeezed out of them. As a result, their might was gone, and all that was left was a handful of pitiful families. There were many families who tried to rebel or even those who disobeyed the Emperor. They no longer existed. They were all killed down to the last child. And it was this cruelty that earned Jircniv the epithet of the Blood Emperor. His rise as the Blood Emperor coincided with the falls of noble authority and the centralization of power in the Empire.

The Five Great Families were referenced by Foresight when talking about Arche Eeb Rile Furt's financial woes due to her parents loss of nobility and denial.
