...could this, if necessary, be used to create a kind of... Emergency Exit, to Hades? If for some reason the Hotel had to be evacuated but returning to the ordinary mortal world wasn't an option?
I'm not too sure, it feels weird to have this stated if it doesn't end up getting used, maybe it's an option in the future if the player has already read the constitution before the event, or if there is a mini game where you try to find a way to abuse the constitution to favour asterion as an insensitive the player to read the in-game lore
