Ferris' Heart

The scent of forest greenery mingles with the ocean in the middle of a forest path. In spite of the sunny weather, the sea breeze makes the air feel cold and unwelcoming. The path ends at what appears to be a large mansion.

On the ground is a small, gold key.

Beatrice's Heart

You find yourself sitting in the audience of a darkened theatre, next to your fellow heart spelunkers. The stage's plush red curtains are currently drawn closed, though there are stairs on either side of the orchestra pit leading up to it. Other than that, if you squint, you can see a couple of side exits to the left and right, and a large pair of double doors behind you.

...However, if you try to move, you will find that your hands and legs are shackled securely to your seats, preventing you from getting up.

There is a foul smell akin to rotten meat.

((ON THE SUBJECT OF MUSIC: Umineko is meta, and so my heartgame shall be. You can hear it if you want, or you can ignore it if you want. But the mood will definitely be there.))
