Underground

The Underground (abbreviated as UG) is a sub-dimension of the Original Universe that was controlled by the Composer and used to host the Reapers' Game. In later years, a warrior from the Dark Universe named Monarch took control of the UG and began to use it to store victims that he had captured from the Original Universe.
