Gatenbarg

Gatenbarg was a human nation that had once existed in the New World, three hundred years ago.

Background
Three hundred years ago, Gatenbarg was a nation founded by humans, who were mainly magic casters living in cities centered around the quick exchange of information using [Message].

However, due to their reliance of [Message], the cities received three falsified messages. This was due to the magic being less reliable as the content of the messages becomes distorted depending on the distance.

Eventually, a civil war broke out between the cities over these messages. The infighting left the nation in such a weakened state to the point that it was vulnerable of being destroyed during the process as well as when monsters and demi-humans took the chance to invade them.

The Invaders of the Large Tomb Arc
The name of this country was reminiscenced during the imperial meeting of Emperor Jircniv, Fluder Paradyne and imperial servants in the imperial palace about the reliance of [Message].

Legacy
The tale of its downfall is a cautionary warning to other countries and people to prevent the over reliance of [Message].
