If the sinking of the Aesirland Empire was directly related to the loss of control of one or more Great Calamity Curios... then the shattering of the grand barrier and the subsequent collapse and plummet of the imperial capital were explicable.

Ivan shook his head, "Our Winter clan is indeed a family with an extremely long history. But we were not in existence from the beginning… It was not until the late third era that we began to act as wardens of great artifacts.
"Before us, the 'Frost Speech' clan, which has an even closer relationship to our grandmother, was in charge of these artifacts. You know the 'Hairdresser' of Razor Ridge, right? He is a member of the Frost Speech clan."
The late third era?
