Hall of Infinite Doors

You stand perfectly still. The beast leans in to sniff at you, and it takes all your willpower not to freak out. Still, the stranger was right. He walks away.

You head back over to the ethereal glow, where the stranger has almost finished freeing everyone. When the last soul enters the last body, everyone steps back. Without any souls to enhabit the glow, it expands, sending everyone home.

Except for you.
