So, having just gotten into the Persona 5 fandom/hype myself, I've been daydreaming a lot about what my own Palace or Personas might be like.
For a palace, though I don't feel I have any twisted desires, I believe it would take the shape of a haunted mansion, with ghosts acting as voices of ideas and people, positions and concepts, full of locked doors and impossible passages. No idea what the treasure would be.
For a persona, I feel like an apt option would be Janus, the roman god with two faces, bearing theater masks of comedy and tragedy, dressed in the garb of an old English butler.
What would you believe Palace or Persona be?
