Firbolg

Distant cousins of Giants, the first firbolgs wandered the primeval forests of the multiverse, and the magic of those forests entwined itself with the firbolgs' souls. Ages later, that magic still thrums inside firbolgs. A firbolg's magic is an obscuring sort, which allowed their ancestors to pass through a forest without disturbing it. So deep is the connection between a firbolg and the wild places of the world that they can communicate with flora and fauna.
