Hm... mine would probably be some sort of dark but intricate garden, probably with some extremely large hedge maze or something. Might be connected to a forest that is even darker. It would always be night there.

My shadow could be a monster form of me, basically. Possibly something that looks like a werewolf.

As for my treasure..? Hm... I am unsure. Perhaps a physical item that represents my humanity, I don't know what that could be though.

I have picked everything to best represent my darker parts. My tendency to act as a horrible person- a monster- in order to keep people away from me at times. I hurt people to keep them away from the monster I think I am.

My palace would probably be planeptune and my treasure would be my pc

Cos I'm a little bundle of sunshine or something, my shadow would be mara cos I'm kind of a dick

These are perfect.XD

If you remember mitsuos dungeon from P4, either that with the treasure being a shield and my shadow an armored knigh. Or something kinda like kamoshidas castle crossed with a creepy dark funhouse, treasure is still a shield, and my shadow being a jester.

Mine would probably be a combination of fantasy and sci-if. Kinda like the Data Castle from Saints Row 3. My shadow would be incredibly lazy, demanding that people appreciate him for his hard work, while also hating anyone who ask him to do something.

The awakened form of my shadow would probably be a torn doll sitting o a throne.

Mine would probably be a massive video game and anime themed mansion because that's really all I desire. The treasure would be some sort of figurine.

My palace would be a creepy hospital because I've had a lot of medical stuff in my life. My Shadow would incorporate my conditions into its fighting style, and my treasure would be a medicine that could fix all of them at once.

Mine would probably be some sort of labyrinth with no escape, because i often feel unable to improve, trapped in mediocrity. The theme would probably be greek, with my treasure being something like Icarus's wings for me to escape with. In reality it would probably be somebody else's art.

The worst part is even knowing how i feel and admitting it can't change it.

If I had a palace, it would probably be a classroom or school, considering that I value academics very much. My shadow would probably be hooked up to a lot of computers or maybe surrounded by extracurricular supplies i.e sports equipment or instruments.

Probably a lot of zio and physical attacking on my shadow's part.

I have a follow-up to my last post. The music in my palace would have a very melancholy sound to it, like Mad World by Gary Jules.

I think it would probably be a casino. No idea how I know this though.

Music... maybe i should change my choice, I have a better Idea.

A big carnival and you got much songs which have a more diffrent things like:
Set it off- Freak show
or Melanie Martinez- Carousel.

Treasure stays the same, but Shadow could be like a Circus director and the other Shadows dress as clowns or Acrobats.
