Unrevisitable locations

Unrevisitable locations are locations accessed automatically during the storyline which cannot be returned to after a certain point in the game. They can typically be visited once and players aren't usually warned in-game that they won't be able to revisit them.

History

Final Fantasy Adventure & Adventures of Mana

The battle arena and prison in Glaive Castle is unrevisitable after Sumo slays a Jackal for the second time during the introduction.

The Airship can only be accessed before triggering the cutscene where Julius confronts Sumo on a catwalk while he attempts to rescue Fuji.

The Dime Tower can only be visited until Sumo and Marcie defeat the Garuda guarding the structure, as it will sink into Glass Desert once again.

Once the player completes Dime Tower and uses the waterfall near Glaive Castle to get access to the Mana Temple, the entire world map becomes inaccessible.

Secret of Mana

Potos Village and Potos Falls become inaccessible once the player agrees to leave his hometown to the male NPC on the village southern exit.

The Underground City and the Great Palace can only be visited during the emerged segment of the Sunken Continent and become inaccessible once the player fights the Snap Dragon in the Mana Palace.

Pure Land is only accessible after the Sunken Continent segment and before the party confront the Blue Dragon.

Trials of Mana

Because of how the game allows a selection of characters to be played with, some playthroughs can only grant access to some hometowns after they are normally visited while not choosing a specific character prevents the player from exploring said locations. Also, final dungeons are tied to a specific character, so choosing a protagonist guarantees only one dungeon out of three will be explorable.

If Duran or Angela aren't the protagonist, Altena cannot be visited during Chapter IV. Also, the Crystal Desert and Dragonsmaw dungeon won't be accessible either.

If Kevin or Charlotte aren't the protagonist, Ferolia cannot be visited during Chapter IV. Also, the Jungle of Visions and Mirage Palace dungeon won't be accessible either.

If Hawkeye or Riesz aren't the protagonist, Nevarl cannot be visited during Chapter IV. Also, the Night Cavern and Dark Castle dungeon won't be accessible either.

If Riesz isn't the protagonist, Citadel Laurent cannot be revisited after the Laurent army counterattack in Chapter II.
