Answer: I'm not exactly sure what your question is, but I'm maybe thinking you want know who is speaking in this story and that is ''First person Narrator''. That means that the Narrator in the story is point of view from a person telling their story or a story they made up, and not only that, it could also mean that the story is narrated by one character at a time. It's possible this character might be talking him/herself or sharing an event that they've experienced.
That's all I could help you with. Hope this is what your looking for. Have a fantastic day my friend! :)

"We had passed through long walls of piled skeletons, with casks and puncheons intermingling, into the inmost recesses of the catacombs."
"We are below the river's bed. The drops of moisture trickle among the bones."
These are some sentences that give us the creepy setting that makes for an eerie mood.
