#they're bones belonging to monsters or some magical entity used to strengthen the protective wards on the cabin 🤷‍♂️

Lol a rumor spawns that the Hades cabin is actually built out of bones and corpses and finally someone gets the nerve to ask Nico about it and he's like "well no, it's built out of concrete and other sturdy stones. Yeah there's a couple dead people in the walls but that's for magical protection integrity, not structural"
