Symbiotic Nomads. The wirbeln fungi's origin is lost to history. Those familiar with the creatures know they are wanderers who roam until they find a suitable home, usually in deep and wild places. Home for the wirbeln fungi is best defined by the deep-rooted companionship they develop with other races, rather than a specific location. The wirbeln fungi form allegiances with numerous species, such as elves, gnomes, treants, and others.
