In the film Pirates of Caribbean: Dead Man Tell No Tales, we learn that "Black rock island" is perfect a reflection of the heavens.
"Look at it, Jack. It's the most beautiful thing I've ever seen. This is what my father wanted me to find."
"No, not rocks. Stars. This is the Map No Man Can Read. This island is a perfect reflection of the heavens."
―Carina Smyth and Jack Sparrow
But we know that the sky changes over the year. So does the island also change with it?
