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 cannot be entered during the daytime because there is a guard blocking the way. The player must enter the castle during the night by staying on the world map until the moon rises.
Since the cavern is covered in darkness, it is advised to use a Torch. The caverns serve no 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.
