Question: What is the mortician carving into the skin of the stolen dead bodies?
Question: Shouldn't the bodies have rotted? They've been inside the walls for decades, yet still look as if they'd been dead for a couple days - maybe weeks.
Answer: It could be supernatural, but my guess is that the bodies were preserved with embalming fluid. the eyelids didn't decompose so they were preserved too. It wouldn't be too hard to acomplish since it was done in a funeral home by a mortician with a lot of expierence.
I would say that it's because the bodies are processed as they would be in a morgue. Since that's what the house used to be 'officially' before they bought it as a house. That's why the rent's so cheap.
Chosen answer: Nothing specific, the carving of mystical symbols is just meant to be a means of furthering his power.
