Kimah led the Sharnazim before ascending to the throne as Zakhan of Vassagonia with the the death of Moudalla in MS 5055. He reigned for six years, during which time Vassagonia served as the only major ally of the Darklords of Helgedad in their campaign to conquer central Northern Magnamund.
Vain and arrogant, Kimah possessed incredible willpower and he could hide his thoughts even from a Darklord, a trait that allowed him to negotiate being given the Orb of Death by Archlord Haakon in exchange for both Lone Wolf and the Book of the Magnakai even though he had possession of neither at the time. Events surrounding Kimah after his receipt of the Orb are unclear: the Legends of Lone Wolf novels tell of Kimah's imprisonment in his own torture chambers by Drakkarim and the throne's passage to a popular rival, while there is no indication that his rule meets with any interruption in the timeline set by the game books.
What *is* known is that Kimah personally led Vassagonia's armored legions during their participation in the Siege of Tahou in MS 5061, during which defending soldiers found that the Orb of Death made him invulnerable to ordinary weapons. After gaining entry to the city, Kimah fought the Kai Master Lone Wolf and was killed. The death of the Zakhan led to the collapse of his oppressive regime and the withdrawal of Vassagonian troops from all of the lands that they had previously occupied in support of the Darklords' campaign of conquest.
