Dungeons have appeared ever since the dawn of time. They are said to have simultaneously sprung up from both the ground and sea without warning even as civilization arose. The first dungeons dated back to the Ancient Scriptures in Raam, a country of the Southern Continent, Erde. Raam has its unique language that has been used by the Divines. It was called Rimal by the oldest tribe in the world called Rim.
The Holy City had many branches, but the Holy Church was only located in Raam where history about the world was written. At least, the history as the tribe had known.
