Playing on the pre-established twin planets Romulus and Remus, the grey-skinned Remans are a slave race, toiling as forced laborers and shock troops. The biggest wrinkle "Nemesis" introduces to the Romulans is the Remans. It turns out Shinzon is a failed clone of Picard, the product of an aborted spying operation. The Romulan Senate is assassinated by a bio-weapon and a new Praetor, Shinzon (Tom Hardy), seizes power. The Romulans finally got a silver screen spotlight in "Star Trek: Nemesis," the final "TNG" theatrical film.

Thus, the Romulans join the war as allies, and remain so until the series' end.

When their deception is revealed, Garak (with Sisko none the wiser until it's done) pulls a move the Romulans would be proud of: he assassinates Vreenak and frames the Dominion. In the season 6 episode, "In The Pale Moonlight," Captain Sisko (Avery Brooks) and Garak (Andrew Robinson) falsify evidence of the Dominion's plans to invade Romulus and try to sway Senator Vreenak (Stephen McHattie).
