This was my theory about the GC that I posted in another thread.
I got it all worked out now. The villagers destroyed the artifacts from the first tribe (the temple, chipped the magic statue down to a rock, damned up the lagoon, buried the treasure) because they knew that while the magic idol was standing (when you rebuild it, it says it was as if the idol was always in the rock), the "cursed child" could be born by baptizing a baby in the lagoon. When performing a ceremony at the temple with the buried artifacts, he would regain his power. With his power back, he could ring the gong to bring forth a great evil.
In the next village(VV3), the child is locked up in a cave. The people destroying the artifacts attacked the first village, and captured the child (now fully powered), and are now looking for a mystical dagger, the only weapon that can kill it. Of course, your villagers don't realize it is evil until after the solve a puzzle to free him, and he runs off, leading from there into VV4
