Tournel was a member of the Ba'ku observed by the Federation in the 2375. He was a friend of Sojef and one of the village leaders.

He, along with Sojef and Artim, met with Anij and Jean-Luc Picard to discuss the "real" history of the Ba'ku people.

After the holoship was discovered and Picard decided to help the Ba'ku, Tournel climbed the bell tower, rang the bell, and shouted to his fellow villagers, "We're leaving the village!" In the caves, he was one of the main organizers, along with Anij, ensuring that the evacuation went smoothly. (Star Trek: Insurrection)
