Katongo is the eldest of the royal sons in the Bemba origin charter. Blinded by his father Mukulumpe as punishment for the collapse of the tower the princes had built, he stayed behind in Kola; when Mukulumpe feigned reconciliation and dug a concealed game-pit to kill the recalled exiles, the blind Katongo warned Chiti and Nkole with a drummed message, enabling the migration to proceed.
