Looking for the Guardians[]
In this shrine are not only one but three statues of guardians, which the heroes seek to finnd. When they arrive at the scene and enter using the magic of the Tear Drop they are surprised by Boomerang and Luceid once again.
After the fight ends boomerang says should congratulate the group but they still are not prepared to face it and says that while they do not unlock the secret of the desire to master the eternal power to be victorious
After entering the room they collect items from the statues: Dragon Idol, Godness Idol and Lion Idol.
The guardian's voice can be heard by the group, they claim to be the fossilized essence of Courage, Love & Hope. They explain that it can no longer materialize, since the people of Filgaia have lost these feelings they have become increasingly weak.
