User blog comment:Zaarqawi/Why players from YGGDRASIL have been transported to the New World at various periods of time./@comment-88.238.138.56-20151108150130/@comment-210.186.232.186-20151109025525

The world items are powerful but most powerful ones are designed to change aspects of Yddrasil  world once used. None of them are capable enough to create an entirely new world and their power in Yddrasil is based on pre-existing programming. But somehow Nazarick were transported to an entirely new world. Your conjecture is the character is trap in a like SAO world. Mine conjecture is that Nazarick was entirely transported to an alternate reality similar to the characters of Log Horizon.
