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, which internally led to their nation's downfall as a whole. This was due to the magic being less reliable as the content of the messages becomes distorted depending on the distance.

A civil war broke out between the cities over these messages. The infighting left the nation in a weakened state and as a result, it left itself vulnerable to be destroyed, when monsters and demi-humans invaded.

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