The Cloudrunner Bloodline
 
The Cloudrunner bloodline, found mostly living in high-altitude areas,
has several distinctive features: First, its pureblooded members all have
snow white wings veined with black.  Second, the more Cloudrunner blood a
sprite has, the better he or she can survive extreme cold.  Third,
Cloudrunner people include among their small number some of the most
powerful of the sprite mages.  Anyone with any blood links to the
Cloudrunner are subject to speculation about whether or not they will be
more magically inclined than most other sprites (and that's saying a lot, as
sprites are magical in nature).  Cloudrunner sprites are generally short and
stocky compared with other sprites.
