Xiuhtecuhtli ("Turquoise Lord" or "Lord of Fire"), was the god of fire, day and heat. He was the lord of volcanoes, the personification of life after death, warmth in cold (fire), light in darkness and food during famine. He was also named Cuezaltzin ("flame") and Ixcozauhqui, and is sometimes considered to be the same as Huehueteotl ("Old God"), although Xiuhtecuhtli is usually shown as a young deity. Xiuhtecuhtli is a manifestation of Ometecuhtli, the Lord of Duality, and according to the Florentine Codex Xiuhtecuhtli was considered to be mother and father of the Gods, who dwelled in the turquoise enclosure in the center of earth.
Children of Xiuhtecuhtli are able to increase heat around a small area somewhat like a force-field. This dries up all life around an area and slowly burns anyone in it even the conjurer in a slow rate.
Children of Xiuhtecuhtli are able to conjure a firewall that blocks and burns most attacks. The bigger and the longer the wall is used, the more it drains.
Children of Xiuhtecuhtli rarely are able to manipulate lava. They can summon small volcanoes in the ground and telekinetically manipulate the lava into a stream which burns anything in its path. Xiuhtecuhtli's powers limit the use of this power.
