An Archaeologist's Memoir of Meeting Magisters

Archaeologist: When I first heard about the beings called the Ancestors, I thought that everybody was trying to fool me.

Archaeologist: There once existed a race of ancient humans who possessed technology far superior to that of our current age… no chance.

Archaeologist: However, once I noticed that not a single one of the Magisters was smiling, was when I realized.

Archaeologist: They were not joking.

There was a forgotten civilization, a past during which humanity had reached unimaginable levels of development.

Archaeologist: They provided several articles of evidence.

The massive underground ruins, the titanic sphere floating in the sky, and a hollow large enough to swallow a mountain.

Archaeologist: It was just as the Magisters had described.

The world was full of mysteries that we could not yet explain.

Archaeologist: Of these, the most inexplainable one is The Old Mystery in Hagios.

Archaeologist: This structure, which was simply called The Old Mystery since ancient times, was said to be an Ancestors' structure.

Hearing that was more than enough of an explanation.

Archaeologist: Mysteries that cannot be understood by humanity were crafted by their hands.

Nothing could be more magnificent.

Archaeologist: We must explore their ruins and discover their secrets as soon as possible.

What were they thinking as they created these mysteries, and what other secrets did they bury?
