Revered by the Native American Magical community, the Thunderbird is an intelligent, temperamental magical North American bird that has the power to create storms as it flies. Thunderbird wands are held to be extremely powerful, capable of performing very advanced magic, though extremely difficult to master. This core produces wands that demand staying power and strength of purpose in their owner, and are poor tools in the hands of the changeable and indecisive. The Thunderbird is so sensitive to supernatural danger that wands created with its feathers have been known to fire curses preemptively. They are particularly prized by Transfigurers. It is also said that Thunderbird wands favour adventurers.
