Takvi was a Romulan officer who served as the chief engineer of the IRW Honor Blade in the mid 24th century. He was a wise and veteran officer who had served for many years with his commander, Charvanek.
As the Honor Blade took hit after hit in the battle of Narendra III, Takvi worked diligently to repair the ship's systems. However, Takvi was gravely wounded in the deadly struggle; as he lay dying in Charvanek's arms, she wished him a safe journey to the Halls of Erebus - the Romulan afterlife for the honored dead - at which point she snapped his neck, ending his life.
