The interior of the vault

The Gateway to the Lost City was an Isu vault located beneath the Greek island of Thera. It served as a gateway to the underwater city of Atlantis.

The entrance leading to the vault laid among the Minoan Ruins on the island. It was these ruins that had at first drew the attention of the philosopher Pythagoras.


In the mid-5th century BCE, after managing to find his way into the vault, Pythagoras spent the next few decades researching on the vault, including its connection with the Staff of Hermes Trismegistus he had in his possession.[1]

By the time of the Peloponnesian War, he'd figured it out and charged his daughter, the misthios Kassandra in securing the relics required.[2]
