The Lord of the Rings: Shadow of the East
Black Spirit Hunters
The Black Spirit Hunters are the tribe of Easterlings to which both Ganoveth and Ariunaa belong. Long ago, the tribe was taught the powerful art of trapping a Maiar spirit within the weapon used to slay it. Further, they were shown how to embody that spirit within a mortal form and nurse it toward a slow spiritual redemption.
One of the weapons used by the Black Spirit Hunters is called Ebonrath-Sahil. It’s currently wielded by Ganoveth. A fire-spirit known as The Speaker is trapped in the blade and is embodied in the form of Ganoveth’s younger sister, Ariunaa.
