The ancestor who founded Tongo was Mosuor, the paramount chief of Mampurugu.
He had to flee the country after being vanquished in a fight for the chiefship. When he reached Tongo, the Gbizug Tendaana, ritual office of the Custodian of the Earth, Genet, was living there. Mosuor came to the house but found nobody there; Tendaan Genet, having seen him coming, had fled to nearby hills. Near a stream not far away, he found a pit. Beside the pit was a tree that was shedding its leaves. Mosuor could see that someone had been carrying water that had spilled onto a path that led to the hills, so he scattered the leaves on the path and hid. After a time, Tendaan Genet came along to get water, the leaves crunching and betraying his presence. The ancestor Mosuor asked him what he was afraid of. Genet said that his gown and the red thing on his head frightened him. When Mosuor found that the Tendaan owned the house, he said that he would stay there with him. Genet would be his Tendaana to carry out the sacrifices on his behalf. Tendaan Genet told Mosuor of his kinsmen, the Ba'at-Sakpar Tendaana, the Wakii Tendaana, the Degal Tendaana, and the Ka'ar Tendaana, the original inhabitants of the country. They sprang from the earth itself, say their descendants.
