Z'Thar the Blood Binder was Hrr'Ta the Moon Seer's partner.
Z'Thar's title comes from a very old line of warriors. The Blood Binder line was a line started in the first wars of Entherstia. The first of the line was Ae'Kanos, He who Binds the Two Bloods. There are many subsets of this line, such as The Blood Binders, the Two Bloods, the Of Twos, and some more distorted ones.
