The Sovrans: Kinship Marriage

Marriage and marital relationships between members of the same House is strictly forbidden by this Sovran. 

While it is considered a great taboo, it has long been considered a crime that only gods can properly punish. While those who engage in it are met with revulsion or pity; it is their children who are most often forced to bear the consequences.

The consequences of this taboo range from physical maladies to lifelong curses too varied to discuss including blindness and a propensity toward violating the other Sovrans across multiple generations.
