Belief is at the core of the story, isn't it? Like, trust is another form of belief. As is faith. Hm.
I'm thinking about the mechanics of the hotel. How much of it showing up for people is because of Hermes mentioning it to someone vs. trust of a stranger to not lie about something ultimately conjuring the hotel to appear for them. Like how the underworld exists in Hades because the residents who live there trust it to exist but no one new is going there because no one believes in it anymore. So maybe Hermes starts the trend of getting people to believe in the hotel, and then people returning from a stay spreading their word of mouth take over?
I'm thinking of how the series might end and wondering if it's possible for the hotel to become a new underworld since it's already been reformed into something resembling Asphodel Meadow. Lots of half-formed ideas, but I think, to be honest, that Asterion is going to ultimately reject leaving the labyrinth based on what happens in the ruthless route.
This has been late-night thoughts while waiting for food. Cue cue out. *salute*
