Nature's Shadow (Ninja Archetype)

From publisher blurb: The art of ninjitsu is not used solely by assassins and thieves. Some ninjas eschew traditional teachings to instead restore balance to the natural world or to protect the flora and fauna of the place of their birth. These crusaders for nature are seldom seen by visitors to their lands, and one who would seek to pervert the natural order may only see one of nature’s shadows once, just before his demise.
