Abra and Bohen were two Vahnatai of the Olgai tribe who worked together, performing various missions for their people. They are particularly known for waking many groups of Resting Vahnatai, and for killing hydras. There is some confusion regarding Bohen, who has been reported to be both a bitter warrior and a thoughtful Ihrno.
They have had several occasions to have contact with notable humans. In 823 IE the Empire War Heroes helped the two wake one group of Vahnatai, in exchange for a soul crystal from Abra. In 833 IE, while exploring a Vahnatai ruin on the surface detected by Avernite spies, the two came across a horde of undead and were aided by the Surface Explorers.
