Kullth was the first High Priest of Mancos and the first Emperor of the Manconian Empire. He was also Mancos' right hand mortal in The Wyrm Wars. Mancos ordered him to create an organization to worship him and an army to support his plans to bring order to the world of the Shattered Kingdoms. This was the founding of the Church of Mancos and eventually the founding of the Manconian Empire. Kullth was highly successful in building the army, creating one of the largest armies ever seen in the Shattered Kingdoms. He led them in countless battles, often successfully. His weapon of choice was a spear which was given to him by Mancos himself, a weapon now known as the Spear of Kullth. At the end of They Wyrm Wars he gave his life for what he believed in and saved his lord, Mancos in the process. After his death he was raised to sainthood by the Church of Mancos.
The Manconian Empire also honored Kullth by naming the fourth month after him. There is a week long mourning of his death and a celebration of his elevation to Sainthood. Even after nearly three thousand years, Kullth is still celebrated throughout the remains of the Empire, especially within the capital.
