Great Houses of Xeblisau
Xeblisau lies in a region with a long history dating back to when humans first arrived on the continent. Over the thousands of years since that time, there have been many great families that have risen to power - at times ruling as kings and queens, or simply powerful and wealthy merchants.
In modern Xeblisau, these great families are not in direct control of the nation - rather, that is a job for the Monarch of Xeblisau. But they still hold great power in deciding who that monarch is, a tradition dating back from the founding of the nation. Twelve of Xeblisau's original seventeen great houses still exist.
Several of the original great houses have fallen since Xeblisau's founding. Their names remain on registers of houses allowed to vote on the next monarch, but with no provable heirs still existing, their votes remain uncast.
Though these houses have existed for hundreds of years, and wield immense power in the nation, the houses have little legal difference to commoners other than their ability to vote on the next monarch. There is no formal noble class, nor noble titles other than monarch.
Structure
The great houses of Xeblisau are very similar to the noble houses of other nations, but are much, much larger. Though the genealogy of noble families and political marriages still hold great power in determining who leads the houses, they also act much like common guilds. Lowborn commoners seek to join the houses to apprentice under master tradesmen, form business connections, and pledge their loyalty.
It is extraordinarily rare to change your allegiance to a house once you have pledged it.
Each house tends to be associated with certain businesses and cultural values.
