Snakeborn

A mostly Yuan Claw Noon Claw who is lead by an enigmatic Master who was pivotal in staying the hand of the Yuan-Ti during the War of the Scale. It is noteworthy that the master is a Yuan-ti and there are both Yuan, Yuan-ti and Black Dragonborn among its pupils. 
This Claw worked behind the scenes for hundreds of years to create a situation where peace would be possible, including sometimes unsavory things like assassination and even the poisoning of an entire Yuan-ti temple all to match the designs of the Claw-Master. 
After the war was over, the Claw Master passed on stewardship of the Claw to a pupil before disappearing, bidding his pupils to forget his name and only remember that his actions were for the greater good.

Yuan-ti
The Yuan-ti of this world are as varied as the species of snake, or the vagaries of the humanity from which they stem. They owe their existence to the goddess Rashashana and they worship her and her various children, the degree of which and what gods take precedence depend on the particular temple.
Black Dragonborn
Black Dragonborn are the most fiercely independent of the pure-blooded Dragonborn, taking after their progenitors in that way. They often only form close ties to their immediate family and a few select friends and trend towards Neutral and Chaotic alignments. Unlike their progenitors, they are often good parents, taking care of and loving their children is the norm even if they do not tend to associate with other families.
The War of the Scale
A vicious war that lasted for 300 years and ended 20 years ago between the various Black Dragons that make their home in Solags Folly and the Yuan-ti temple cities there. It brought the Black Dragons on the archipelago to the brink of extinction before an unforseen alliance between several black dragon females created enough strength to withstand the Yuan-ti and force a stalemate.
