Deep Purple

This is from an old drill site located on Pebbles' grounds. There are similar ones here, quite ancient machinery.

When you drill deep under the earth, you never really know what you'll find.
Of course, you'll always end up in the Void Sea.

But the strata between the surface and the deepest depths are full of surprise.
This world is but a stack of ancient civilizations eager to leave their mark.

I have very good reasons to believe my island is simply a giant tumulus of ageless remains.

...

What a charming thought...
