The Empty

"The next time you or your brother bite it, well, you're not going to Heaven or Hell. One of us, and lord I hope it's me, we're gonna make a mistake and toss you out into the Empty. And nothing comes back from that."

- Billie

The Empty is a void where souls can be placed rather than Heaven, Hell, or Purgatory. It is said that once a being enters the Empty, it is impossible to resurrect them. It was mentioned by a reaper named Billie to Sam Winchester when she told him that he or his brother will be sent there when they die.
