The Dungeon is a formidable cave located in northern Lorencia It was once an underground prison, but is now a den for Kundun's Army! The fierce Gorgon awaits anyone who dares to challenge him, at the end of this treacherous chamber. Once managed by the Church of Devias, this cave was used as a prison for the empire. Guards could be found here, in numbers, providing service of justice for criminals. For the most part, no MUtizens enters the Dungeon anymore, except for experience warriors looking for some loot. This place has become plundered and lays in ruins. There have been many tall tales about great treasures hidden within the Dungeon, however no warrior, which came back alive, has ever returned with much more than typical loot.
