This castle... It feels... Odd..

The darkness fulfills your fear, in hopes of finding someone there.

There's a bridge in the path, the only thing below it is only lava and fire.

You proceed to go further and then stop at the bridge, just to look at the window for a moment.

Just until someone walks in and ruins everything. And that someone is...

Luigi.
