A former Romulan senator stranded on the relocation world Vashti who confronts Picard over the Federation's abandoned rescue effort in 2399 and is killed by Elnor when he forces a duel.
Tenqem Adrev appears in the first-season Picard episode Absolute Candor. Once a member of the Romulan Senate, he is among the refugees settled on Vashti during the evacuation, and by 2399 he is a bitter regular at a Romulans-only social club in the settlement of North Station.
When Picard returns to Vashti, tears down the club's segregation sign and sits down inside, Adrev challenges him. He accuses Picard and the Federation of scattering his people and then walking away from them, and tosses him a sword so the matter can be settled by combat.
Picard refuses to fight properly. Elnor, newly bound to Picard's cause, steps in and asks Adrev to choose to live; when he does not, Elnor beheads him, to Picard's fury.
