Lakanta was apparently a tribal member of the Native American civilization on Dorvan V. In 2370, he approached Wesley Crusher, whose spirit was troubled as to his future. Lakanta told Wesley that he saw Wesley in a vision quest that he performed and had been waiting two years to meet him. Lakanta told him that he could provide answers to his questions.
He took Crusher to a habak, a traditional Indian place where one could begin a vision quest. Crusher met his deceased father in his vision quest who told him to follow his own path, not his father's path. After Crusher helped stop a war between the colonists and Cardassians, Lakanta revealed his true identity as the Traveler. (TNG: "Journey's End")
