A Starfleet vessel of the 32nd century that was boarded in 3190 by the Qowat Milat nun J'Vini, who stole its dilithium and killed one of its officers.
The USS Credence is a Starfleet ship of the rebuilt Federation. It appears at the opening of the Discovery episode Choose to Live, set in 3190.
The Credence is delivering dilithium when a small group led by J'Vini, a sister of the Romulan Qowat Milat order, comes aboard. They take the dilithium, and J'Vini kills a Starfleet officer who tries to stop them.
Because the killer belongs to an order based on Ni'Var, which is still negotiating its return to the Federation, the pursuit is run jointly. Michael Burnham and Tilly join Gabrielle Burnham and other Qowat Milat to track J'Vini, and find that she stole the fuel to protect a ship of aliens asleep inside a hollow moon.
