Playable on a hero company during your orgazniation phase if you discard a ranger character from your hand. All characters in the company this turn receive +2 prowess against attacks keyed to Wilderness [w] and during combat at Ruins & Lairs [R].
"Each company was guided by a wild woodman...the thickets offered to the Riders their last hope of cover before they went into open battle."
