Overseers are the most dangerous of the beholderkin. Rivaling the power of a hive mother, an overseer resembles nothing more then a large mass of flesh, or a tree with mouths on its trunk and eyes on its branches.
Overseers possess powers similar to that of a Hive Mother and can control the actions of five to ten standard beholders or five to twenty beholder-kin. However, overseers can only control creatures of the same type. Thus, one overseer could control death kisses or directors, but not a combination of the two beholder types.
