A Vulcan admiral at Starfleet Command during the Federation-Klingon War of 2256, who gives Captain Gabriel Lorca his orders by holographic link in the first season of Star Trek: Discovery.
Terral is played by Conrad Coates and appears in Choose Your Pain, Lethe, Si Vis Pacem, Para Bellum and Into the Forest I Go. He is usually seen alongside Admiral Katrina Cornwell, or speaking for Command once she has been captured by the Klingons.
He takes part in briefing Lorca on the importance of the spore drive and in the decision to limit its use so the Federation's one great advantage is not lost. He takes a dim view of Lorca's unauthorised rescue of Sarek.
When the Klingon Ship of the Dead approaches Pahvo, Terral orders the Discovery to withdraw to a starbase rather than fight. Lorca finds a way round the order and destroys the ship, after which Terral tells him he is to be decorated.
