Path of the Beast Master

The Path of the Beast Whisperer was paved by a druidic barbarian known as Valgryn, she forged the path, and taught it to others. Beast Masters fight beside a trusted animal companion, usually in the form of a wolf or bear, though there is no restraint for companionship. Beast Whisperers are masters of fighting side-by-side with an ally, gaining certain advantages. 

They are also adept in traversing, knowledge, and communing with nature. Most Beast Whisperers vow to protect nature from the destructive grasps of certain people.
