At that time, centered around the Sixth Ring Tower, a giant city had already been established, with millions of inhabitants.
The Sixth Ring Tower itself was also a remarkably tall building, generally housing many Wizard Apprentices.
After Boas and others took action, they joined forces with several other Wizard Organizations to gather a large number of people, preparing to invade the Sixth Ring Tower.
The main power of the Sixth Ring Tower had been completely diverted to the Abyss Plane at the time, leaving them at their weakest.
If the Sixth Ring Tower hadn't evacuated in time, these people would have died at the hands of Boas and others.
The Wizard Apprentices taken away by the Sixth Ring Tower were extremely crucial, bringing a massive population for the development of the Boundary Land later on.
Without these people, the Boundary Land wouldn't have been able to be established and developed.
