It's something we create ourselves and nothing that exists already, right? Asked because I'm not too familiar with the Persona games so I wasn't sure about the Mirror world app/etc bit. Though, I'm assuming the dungeon is where we'll find our 'true self'? And I'm guessing the "True Self" is our character unmasked, the complete opposite of our characters.....well....everything, right? I know I probably shouldn't worry about this apart until I manage to whip out a CS and actually get approved, but just wouldn't to clear up my confusion.
