The Sunspark Bloodline
This is sprites' "royal" bloodline, sometimes having a yellow or orange
streak on otherwise normal sprite skin or in hair.  Most striking are their
yellow eyes.  Only sprites with two Sunspark parents are born with yellow
eyes, but some mixed-blood Sunspark develop yellow or yellowish eyes later
in life.  While during normal sprite operations, the Sunspark behave and are
treated just like those in the more common bloodlines, in times of trouble,
sprites rally en masse around the Sunspark leadership, as sprites see them
as symbols of their rich heritage.  Sunspark prefer to live in the tropics.
