After leaving Baron Castle, Cecil and Kain stop at the town to purchase supplies for the journey to Mist in the north-west. Cecil later returns through the Devil's Road from Mysidia and finds Yang in the inn, stricken with amnesia and working as a captain of the guards. He attacks the party when they speak to him, as Cecil is an outlaw to the kingdom now, but after fending off Yang he comes to his senses and helps them infiltrate Baron Castle using the master key to the town he has.
When the Red Wings are attacked during Ceodore's training at Mythril and crash at Mysidia, Ceodore and a mysterious Hooded Man who rescued him from monsters return to Baron through the Devil's Road. Later, Kain Highwind uses the Devil's Road to travel from Mysidia to Baron, pursuing a Mysterious Girl who has taken control of the kingdom.
After Cecil deals with the Baron soldiers on the pub upstairs and recovers Yang, the party gets a free stay. Cecil informs the party of his plans to rescue Rosa and help Baron.
Armor & Weapons Shop[]
The shop is located in Baron downtown. It is locked during the first part of the game. After Cecil returns to Baron and fights Yang and the Baron soldiers in the pub, they will acquire the Baron key, which opens the shop. The shop has a secret passage in the southeastern corner that leads to the inside of the counters. The weapon shop chest has Zeus's Wrath, and the armor shop has 2000 gil.
Pub[]
The pub is upstairs of the inn. After Cecil and the party use the Devil's Road, they must talk to Yang, who is in the pub with Baron soldiers. Yang orders the soldiers to capture Cecil and company, revealing that he is under control. After the soldiers are dealt with, Yang will attack, but Cecil has him come to his senses. Yang rejoins Cecil's party, telling him that Rydia was swallowed by Leviathan and Edward's whereabouts remain unknown.
Rosa's House[]
The building is situated in the right side of the town, just north of the inn and pub. Joanna Farrell, Rosa's mother, is the only person in the house. Before Kain and Cecil head to Mist, if spoken to, she will ask the two to leave Rosa out of their dangerous affairs. When Cecil returns a paladin, she asks for Rosa and explains that after he and Kain left, she snuck out. When Rosa is recovered from the Tower of Zot, and if the player drops by again, Joanna forbids Rosa from leaving, but she persists and says she is happy to be a White Mage and help Cecil. With that, Joanna tells Cecil to take care of her daughter.
Cid's House[]
Cid's home is the building found in the upper-left corner of the town. Inside the party can find Cid's daughter, one bed, a workdesk, and three shelves that contain books on shipbuilding and ship history.
Devil's Road[]
Devil's Road is located at the right side of the town. At the beginning of the game, the player can access the building, but the warper is null as the Elder of Mysidia sealed off their side. After Cecil becomes a paladin, the elder opens the Mysidian side and allows Cecil to use it.
Training Classroom[]
The training classroom is downstairs the warping area, located in the Devil's Road building. The classroom contains three soldiers and an old man who briefs the player on the game's battle system. The sentinel guarding the classroom informs the player of the Game Center and the achievements system in the versions that have them.
In the SNES and Easy Type versions, the training room is larger, and not in the Devil's Road building. It has more people and there are duplicates of the training room in Kaipo, Mysidia, and Troia.
* - The vast majority of treasures are within the city, in addition to these there are some in the lagoon outside the city accessed by the water channel (2 items), the grass area to the north by a secret path through the trees to the east of the city (3 items) and the secret passage on the right just before the entrance to the Old Waterway (1000 gil in all versions).
In the beginning of the game, only the Item Shop can be accessed. The second item shop in the 3D version is only available after returning to Baron for the second time.
The background music that plays inside Baron Castle is "Kingdom of Baron", while the track that plays in the town of Baron is the Final Fantasy IVtown theme, "Welcome to Our Town!"
