To put it mildly, we know very few facts about the origins of dungeons and labyrinths. Even in today's society, it remains a popular topic. However, what we can infer is that it is a place that was not intended for humanity or any surface dwellers for that matter.
Scientists and scholars alike have gone as far as to hypothesize that dungeons are designed to keep out surface dwellers.
Numerous pieces of evidence support this claim. For instance, as surface dwellers descend deeper within the dungeons and the mana levels rise dramatically, over time they'd contract an illness called 'Mana sickness'.
It is a disease contracted from being exposed to too much mana. You see, the internal systems of surface dwellers aren't built to handle mass amounts of mana.
This illness has been one of the leading causes of death for a great number of delvers throughout history. Fortunately, due to modern society's advancements, the illness is far less lethal than it used to be.
