The term 'Babylonian Abode of the Dead' refers to two locations in ancient Babylonian mythology. The first is Aralu, a mythical realm of the dead located in the underworld. It was believed to be the final resting place of the souls of the deceased. The second is Hel, a realm of the dead located in the underworld ruled by the goddess of death, Hel. It was believed to be the place where the wicked and damned were sent after death. Both Aralu and Hel were important parts of Babylonian mythology and were believed to be the ultimate destination for the souls of the dead.
