Kamin's closest friend in the community of Ressik, whose memory Picard honored by naming his son after him.
Batai is a friend of Kamin in Ressik on the planet Kataan. He supports Kamin and Eline as Picard adjusts to his new life in the memories transmitted by the Kataan probe.
In The Inner Light, Batai's death is one of the sorrows Kamin endures as the years pass. When Kamin and Eline have a son, they name him Batai in his honor. The friendship is part of the rich community life that leaves Picard deeply changed.
