The Leviathan Coast
Nobles and their supporters believe in the rule of those bearing hereditary titles of honor. This is how much of the Sword Coast has been ruled for hundreds of year, and many of the titles and noble families throughout the region date back at least that far.
Nobles often espouse a belief in patronage and charity. Lower classes, religious temples, and artists are often the recipients of this generosity, and nobles typically expect gratitude and obedience in return.
Nobles rule most of the Sword Coast and are by far the most powerful political faction.
