Eye of the Eastern Sun

The voice said, I'm the Protección Stone guarding Cave Town. My words are everlasting truth as long as this village exists. Thieves stole the two jewels protecting this village and were turned into monsters. Without the jewels, the caves of Cave Town will collapse. Even though people don't live there any more, the caves should still be protected. We should destroy the monsters and take the jewels back. One of the Jewel Land is in the hand of a Euriale here in Cave Town. Dispose of the monster, find the Jewel called the Eye of the East Sun and bring it to the rock south of Ocultarback Village.

Go to the Euriales in Cave Town and find the one who took the Jewel. Take the Eye of the East Sun to the rock south of Ocultarback Village.

When I put the Eye of the East Sun into the rock, I heard a voice say, Good work! But there's still one missing!
