Also known as Shulawitsi or Deputy to the Sun, Little Fire God is one of the titles for the role a young Zuni man performs when participating in the Shalako ceremony, which takes place around the winter solstice. The winter Shalako marks several days of concentrated spiritual observance and ritual practice meant to invite protective spirits into the community, so that sustenance and fertility are ensured. The main ceremony lasts a full night, and involves trained dancers wearing masks and personating the kachina spirits. In the Zuni belief system, the dancers do not simply impersonate the gods, they in fact become the gods for the duration of the dance. The Little Fire God is one of these dancers, and his duty is to follow the righteous path laid out by the Sun Father deity, praying for rain, health, and prosperity for the people. The Fire God is usually a young novice being initiated into the sacred rituals of the Zuni. Preparations for serving his duty include purifying the body, the heart, and the mind of interfering influences by observing celibacy and refraining from negative thoughts and emotions such as anger and aggression.
