A human cadet raised on Titan who joins the reopened Starfleet Academy in 3190 and takes part in the shuttle exercise that strands Tilly, Adira and their trainees on a dangerous moon.
Cadet Val Sasha appears in All Is Possible. She comes from Titan, which was estranged from Earth for much of the century after the Burn, and like her classmates she has grown up with little experience of other species.
Sasha is more level-headed than her quarrelling companions Harral and Taahz Gorev, but she is just as unused to relying on others. After the crash she is among those who must be coaxed by Tilly into sharing something of themselves, and she speaks of her upbringing.
She helps carry out the plan to reach a ridge from which Discovery can be signalled, and is beamed out with the rest as the creatures attack.
