"We can profit from each other here."

After aiding the Illusion Cavaliers, you were told about Ione, a Cavalier well-versed on the situation in the swamp.

However, the journey to meet Ione was far from smooth. At every turn are rifts, corpses, and rampaging Spirits...

After overcoming these obstacles, you finally met Ione, only to learn that the various incidents have caused the Spirit Tree to fail to bear fruit.
