Hell

Hell, also known as the Underworld and Sheol, is an inter-dimensional location where Demons and Fallen Angels reside. It is also where the souls of damned humans are sent upon death and are tortured by the other demons for the rest of eternity. Furcifer implies that some souls who are sent to Hell can become demons as well.

History
After Astra Logue was possessed by a demon, John Constantine attempted to summon a greater demon, Nergal, to expel the lesser demon out of her. However, Nergal dragged her away, killing and damning her to Hell.

When John Constantine turned the Devil's acetate dark magic upon itself and banished it back to Hell, a great red-lit pathway downwards into the ground was left in wake of the acetate's "falling" into Hell.

John Constantine was somehow sent to Hell, sometime between late 2015 and early 2016. He finally got out around May of 2016.

On Earth Nineteen, specifically the world Breacher hails from, Hell is primarily called "Sheol".
