Guera Caverns is an optional location in Final Fantasy: The 4 Heroes of Light. The caverns are located on the bottom floor of the Guera Castle, but they cannot be entered during the daytime, because there is a guard blocking the way. In order to enter the caverns, the player must go inside the castle during the night by staying on the World Map until the moon rises and then entering the town.
Since the cavern is covered in darkness, it is highly advised the player uses a Torch to brighten up the area. The caverns serve no actual part within the story, but the player can find valuable items that can be helpful when exploring the Quicksand Castle.
|Torch||Chest located at the entrance.|
|Wood Axe||Chest in the secret room on the second floor.|
|Ether||Chest in the west corridor of the first floor.|
|Water Tome||Chest on the second floor.|
|Phoenix Down||Chest in the right corridor on the first floor.|
The typical dungeon theme, "Cave of Wraiths" (あやかしの洞, Ayakashi no hora?) is the location theme for the Guera Caverns. The track can be found in the original soundtrack as Track 9 and is composed by Naoshi Mizuta.
