Sotho people [SEP] Cannibalism
According to the Basotho, cannibals are regarded as people having evil supernatural powers comparable with Satan or spirits of the dead that oppose the good spirits and Basotho ancestors. Their tradition states that the great Bakuena chief, Mohlomi, prophesied the coming of the "lifaqane" and cannibalism on his death bed with the words, "After my death, a cloud of red dust will come out of the east and consume our tribes. The father will eat his children. I greet you all, and depart to where our fathers rest."
