Castaway's Journal - Day 13

I've worked out that the ancients must have lived in luxury alongside Pals. Yet, due to some unknown reason, that way of life was lost.
Perhaps it was a massive natural disaster, or maybe a struggle broke out for scarce Pals and resources.
Then again, maybe it has something to do with the teleportation I experienced in the tower. Supposing that some power is responsible for that spatial teleportation (perhaps similar to how the Pal spheres work), what would happen if that power were utilized in other ways?
A power so great that humans could not control it... Perhaps that is what destroyed the civilization on this island.
