Cave of Eblan

The Cave of Eblan (エブラーナの洞窟), also known as Cave Eblana, Cave Eblan and Eblan Cave, is a location Final Fantasy IV that can only be reached via the Hovercraft. It is located southwest of Eblan. The cave is filled with water, much like the Underground Waterway.

Final Fantasy IV
After Rubicante destroyed the kingdom of Eblan, many of its survivors moved to the Cave of Eblan and built a town and barracks. An effort coordinated by Edge allowed the Ninjas to dig a tunnel from the town to the Tower of Babil. As a result, however, much of the Eblan army was destroyed. Edge himself got in a fight with Rubicante and lost just when Cecil, Kain, Rydia, and Rosa showed up. Edge told them to stay out of it, but Rydia burst into tears as a result. Edge could not stand watching Rydia cry, so he agreed to fight alongside Cecil and his friends.

Final Fantasy IV: The After Years
The Cave of Eblan makes a reappearance in Final Fantasy IV: The After Years. From a tower in his castle, Edge notices that the Tower of Babil has been reactivated. Noting that things have started to happen as they did years ago when the castle was taken over and destroyed, he goes to the Cave of Eblan to make his way towards the Tower of Babil. Along the way he notices his father's gravestone and takes a moment to grieve. Right as he gets to the Tower of Babil's entrance, Edge sees Rubicante stand in front of him, but quickly disappear. Then Edge leaves the caves and enters the tower.

In The Crystals, the caves are an optional side area. A tail collector in the cave will trade the player colored Tails for Small Tails, which can only be acquired in this chapter. Seven Small Tails can be traded for any colored Tail, but fourteen can be traded for a Rainbow Tail, the only way one can be acquired. Once the player can access the tail collector's home on the True Moon, these colored tails can be traded for rare items.
