DESCRIPTION

Before the disappearance of an ancient civilization, people used to sacrifice living beings to the underworld, using the souls of the sacrificed to obtain 'Underworld Iron,' a crucial material that supported the construction and development of this mighty empire.

One day, the civilization had grown powerful enough to create a bridge to the underworld, and they launched a massive attack to directly seize the Underworld Iron. However, this action led to their downfall.
