On the first floor of the building, we see a group of people gathered in front of a picture of a saber-toothed tiger. It's clear that the island was a gathering place for people from all over the world to gather and work together. The statue we dug up is in the center of the photo, and it's probably the same statue that was placed on the other side of the island. We learn that the third floor has living quarters, and the fourth floor has a hall where departed souls are supposed to rest.
