Gatenbarg

Gatenbarg (ガテンバーグ) 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 on [Message], problems arose when the cities received three falsified messages. This was due to the magic being less reliable as the content of the messages became distorted depending on the distance.

Eventually, a civil war broke out between the country's cities over these messages. The infighting left the country in such a weakened state that it was left vulnerable to foreign invaders. For instance, many monsters and demi-humans took the chance to invade them while they were facing a dire crisis.

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

Legacy
The tale of its downfall served to be a cautionary warning to other countries and people from completely relying on the [Message] spell as a means of communication.
