A female neo-dolphin, Tsh't is the exploration vessel Streaker's fourth officer. With Thomas Orley and Hannes Suessi she leads the mission to evaluate the uses of the crashed Thennanin star cruiser. When Tom develops a probably suicidal plan to attract the warring aliens' attention, Tsh't reluctantly accepts a key role assisting. She doubts that Capt. Creideiki will prevent the mission, as she believes in secret orders that put humans above the command structure. Tsh't supervises clearing out the great central cavity of the downed battleship. During the escape of the Trojan Seahorse, Tsh't's battle experience is recognized and she is put in practical charge of the bridge by acting captain Dr. Gillian Baskin. She flies brilliantly.
