Sangano was a male Tezwan, husband to Tenila, and father to Neeraj.

During the initial nadion-pulse cannon attack on the orbiting Klingon Defense Force fleet and the Klingon planetary bombardment, Sangano was killed. Tenila buried her husband in Savola-Cov, one of the trinae cities, sent their son Nerraj to live with family, and joined the newly formed planetary peace keeping forces, feeling a sense of duty after seeing the example of Starfleet.
