Draconic Bloodline

(Not to be confused with Dragonborn.)
The Draconic Bloodline is a subspecies of Human that often grants varying degrees of innate magical prowess, generally related to the color of a dragon.
Each Bloodline is directly connected to a different Prime Ancestor; the lineage typically relates them to every Dragon of the same color. 
One of the most well-known Bloodlines is that of the blue Prime Ancestor Thýellus, whose kin include the famed Sorcerer Halcyon Thýella.
