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 ensuing battle. 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.
