House Allemand
(http://i.imgur.com/6uUwF.png)
A family of wealthy merchants who immigrated from Falkovnia, the House Allemand is perhaps one of the main reasons the peace with Falkovnia lasted as long as it did. They primarily traded in grain and this proved fairly lucrative for them, though it would come to pass that not even money could save them from inevitable disgrace. At the onset of the war, House Allemand found its property and massive wealth seized by the Dementlieuse government, under a decree passed by the Lord-Governor.
Rumors, however, spread of the family perhaps making some sort of comeback, supported in part by the Falkovnian diplomat named Marcos Vederrak, son of the infamous Paul Dirac, a wealthy grain merchant of Dementlieuse birth who fled to Falkovnia early on.
House Dauphin

The Dauphins were a family with a long and rich tradition - if anyone could be called "Old Money", it would perhaps be them. They were wealthy beyond measure, and was rumored that they have perhaps the strongest genealogical link to the founders of Dementlieu, possibly to one of the original members of the Council of Brilliance, or even the mythic Emperor Léon. This was not a rumor that the Dauphins themselves discouraged, believing it won them a considerable amount of prestige. The Dauphins endeavored to become the most powerful house in Dementlieu, something that was well within their reach.
It was, however, discovered that the Dauphin family and other nobles indebted to them were involved in a conspiracy aimed at overthrowing the Council of Brilliance. This plot was ultimately foiled, and it is said that the patriarch of the family, Charles Dauphin, was killed near the border shared with Falkovnia.
House Dumonde

House Dumonde is no more. What happened to this once-prestigious house is a mystery...
House Guignol

The family of the Lord-Governor. While he was alive, Marcel Guignol obviously led the family. The Lord-Governor himself was slain via poisoning by a mysterious assassin, likely as part of a political statement in the lead-up to the Revolution of 770 BC. The revolutionaries did not spare a single man or woman bearing the Guignol family name -- all were lined up behind Madame Guillotine, and made to sate the mob's hunger for aristocratic blood.
House Moliére

This family ended when Baptiste Moliére married Linette Jalabert. Unfortunately for Baptiste, he passed away during a fishing incident gone awry.
House Véron

House Véron is but a memory. The last living member of the family, Marc Véron, is an escaped madman.
