what if living people who visit the underworld eventually start the dying process and the “our decay” title is referring to our heroes starting to essentially die. I think it makes sense logically.
Hades, being the land of the dead, not the land of the dead, but the living may come and go as they please, probably has a time limit clause, and any living soul not meant to be there probably has to join the dead by dying.
In the Disney film, when a living person goes into the river of souls, they began to die and wither.
And one of the things we learned in Screenwriting was that to add higher stakes, the writer can give the hero a time limit they need to complete their mission. If the heroes only have, lets say, three days to find Hook or else they die, it make for more drama.
That’s my guess.
