Kull is a powerful warrior who rises to become the ruler of the kingdom of Valusia after defeating the old king in battle. However, the direct heirs of the old king refuse to accept Kull as their ruler and seek to overthrow him and regain control of the kingdom.
They turn to an ancient witch queen named Akivasha, who was reputed to possess immense power and knowledge of dark magic. Akivasha is brought back to life, with the intention of using her powers to help the heirs regain the throne.
But Akivasha has her own plans for the kingdom - she seeks to bring her demon lords to power and rule the kingdom herself. To achieve her goals, she needs the breath of the god Volka, a rare and powerful substance that can only be obtained from a sacred mountain.
Kull, with the help of his companions and allies, must journey to the mountain and retrieve the breath of the god Volka to stop Akivasha and her demon lords from taking over the kingdom of Valusia. Along the way, Kull faces numerous challenges, including battles with Akivasha's minions and treacherous terrain.
Ultimately, Kull manages to reach the mountain and retrieve the breath of the god Volka, which he uses to defeat Akivasha and her demon lords. With the kingdom of Valusia safe once more, Kull is hailed as a true hero and rightful ruler, respected by all who know him.
