Underground (Undertale)

==Summary==
The Underground is the current home of the civilization of the monsters, a species who used to coexist with humans on the Surface. Following a one-sided war, the monsters were sealed in the Underground by the Barrier set up by the humans. Since then, they have waited for humans to fall in the Underground in order to get their SOULs and escape the Underground.
