A Klingon follower of T'Kuvma who serves as his Torchbearer in 2256 and is accidentally killed by Michael Burnham on the hull of the Sarcophagus ship, giving T'Kuvma the martyr he wants.
Rejac appears in The Vulcan Hello, the first episode of Star Trek: Discovery. As T'Kuvma's Torchbearer he guards the ancient beacon on the outside of the Sarcophagus ship, wearing ornate armour and carrying a bat'leth.
When Burnham flies across in a thruster suit to examine the object, Rejac confronts her. She tries to escape by firing her thrusters, collides with him and drives him on to his own blade. It is the first death in what becomes the Federation-Klingon War.
T'Kuvma mourns him with the traditional death howl and has his body placed in a coffin on the ship's hull. The vacant title of Torchbearer is then claimed by the outcast Voq.
