The Baobab Tree of Salaga

Dauda, a twelve-year old boy lives in a village north of Salaga with his parents. He often helps his father who is a blacksmith at the forge. He also grazes their sheep and goats.

One night, slave raiders captured everyone from his village. Dauda gets separated from his parents. He is taken to Salaga where he is chained to a big baobab tree before he is later sold off. From Salaga, he, together with many others are marched to the coast and made to board a ship to the Americas to be sold as slaves.

Two hundred years later, a stranger visits the same baobab tree at Salaga. Who is this stranger?
