Ki Baratan is the capital city of the Romulan Star Empire. Located on Romulus off the coast of the Apnex Sea, the city is sometimes referred to anachronistically by the old name Dartha. Rehaek had a home on the outskirts of the city; in the city, Sela had a townhouse. (ST website: The Path to 2409)

Ki Baratan is the location of the Hall of State; in 2374 and 2379, rioting broke out in the city following the assassinations of Emperor Shiarkeik and of the Romulan Senate, respectively. (ST short story: "Blood Sacrifice", TTN novel: Taking Wing)

In 2382 a food shortage occurred and limited replicator use was put into effect on Romulus. People in Ki Baratan rioted in response to this situation. Up to 2,000 people died in the riots. (ST website: The Path to 2409)

In the Last Unicorn Games RPG, the capital city of Romulus is called Val'danadex Trel. Its position on the coast matches Ki Baratan's, so they are assumed to be the same city.
