In Edge's Tale, Izayoi is undercover in Troia as an Epopt trainee to investigate the city, and upon hearing about the Tower of Trials heads to investigate it.
Spoilers end here.
The town lake is located east of the pub, just before the Black Chocobo Nursery. On the banks, there is an old man taking a look at the bathing dancing girls. If the player talks to the dancing girls in the lake, they will tell him to get out in fear of rusting his armor.
Black Chocobo Nursery
The nursery is the building farthest north in the town. Two black chocobos are shown on the second floor. All non-playable characters inform the player about why black chocobos are only found in Troia, where they can travel, and how they are grown.
Like most other towns, Troia has a pub of its own. A non-playable character guards the entrance to the King's Bounty Pub, and unless the player buys the 100,000 gil Member's Writ from the girl near the entrance, the exclusive pub cannot be accessed. If the player has talked to Cheatingway back in town, and if the girl in the counter is approached, a scene will trigger: Cecil will ask for milk to buy Cheatingway time until he arrives. The music box will then be unlocked. The pub also has a second floor, where dancer girls are mingling with some townsfolk.
King's Bounty Pub
The Bounty Pub is an inaccessible area because it is guarded by a non-playable character, and unless the player purchases a Member's Writ, he will deny the party access. A secret passage leads to the room, and when the player talks to the man in the counter, six dancing girls will put on a show. In the room, there are three throne seats, and the player will sit on the middle one as the girls dance.
The dressing room is accessible via a secret passage found behind the right chair. The only occupant is a dancing girl who informs the player that the room is used for dressing. Also, the Gil Farmer augment is found here.
