The Passage of the Eidolons (DS/iOS).

The entrance to the Feymarch, hidden on an island within the earth!

The Passage of the Eidolons (げんじゅうのどうくつ, Genjuu no Doukutsu?) also known as the Cave to the Phantom World, is a location in Final Fantasy IV and its sequel Final Fantasy IV: The After Years.

Its caverns link the Underworld to the Feymarch, land of Eidolons. The cave is littered with many lava-filled pits, which will damage the entire party if stepped on. Rosa can prevent this damage by casting Float on the entire party. The spell will need to be recast whenever a new floor is reached. On the third basement level of the Passage, a blue prism awaits that will teleport the party to the Feymarch.

In Final Fantasy IV, The Passage of the Eidolons is a completely optional dungeon and as such may be accessed at the player's leisure. It is only accessible after the airship Falcon is obtained, though the player may wish to level up their party first in order to be prepared for the tough monsters that nest in the cave.

In The After Years, it is part of the storyline and is thus required to be visited.

  • Interestingly in The After Years, the party will not be hurt by stepping on the lava-filled pits. This is due to the lack of a usable White Mage character that can use Float during Rydia's Tale.
