Tiris Jast

Bolian Starfleet Commander Tiris Jast was assigned command of the starship USS Defiant early in the year 2376.

Jast arrived at the station during the N-Vector viroid incident, and got off on the wrong foot with station commander, Colonel Kira Nerys, but the two eventually earned each others respect.

Jast was in command of the Defiant and patrolling the Bajoran sector when the ship was temporarily caught in a warp Dead Zone.

Jast was killed in action onboard the Defiant in April of 2376 when the ship was attacked by a trio of rogue Jem'Hadar vessels.
