Amongst the Nama two prominent figures stand out in their religious mythology. The first is Tsui-//goab, the deity who was sometimes seen as the founding ancestor of the Khoikhoi. He was 'the creator, the guardian of health, the source of prosperity and abundance, and above al the controller of the rain and its associated phenomena of clouds, thunder and lightening.' By contrast, //Gaunab was 'primarily an evil being, who causes sickness or death.' The other major figure is Haitsi-aibib, a folk hero and magician of great repute who could change his form. Haitsi-aibib died many times in different places, but had the ability to come to life again - often being reborn in a different form. His 'graves' are widely distributed, and it was seen as good luck for passers-by to add to the piles of stones already there, or to leave branches, pieces of their clothing, or skins.
