Antlion's Den

The Antlion's Den, also known as Antlion's Cave, is a location in the game Final Fantasy IV. It is the cave that contains the nest of the Antlion, which lays the Sand Pearl, the only known cure for Desert Fever, among its eggs.

Final Fantasy IV
Cecil Harvey, Rydia, and Edward Chris von Muir came here to find a cure for Rosa Joanna Farrell's Sand Fever. They reached the Antlion's nest, and Edward tried to take the Sand Pearl from the usually tame Antlion. However, the Antlion became aggressive, and Cecil's party had to defeat it. They succeeded, and returned to Kaipo to heal Rosa.

Final Fantasy IV: The After Years
Edward comes here to retrieve a Sand Pearl to heal Harley of her desert fever. After obtaining the Sand Pearl (with little effort), Edward returns to Kaipo to save Harley.
