The Empty

"Cosmic Entity: Before God and Amara, creation, destruction, Heaven, Hell, your precious little Earth, what was there? Castiel: Nothing. Cosmic Entity: Yes. That's right. Nothing. Nothing but empty and you are soaking in it. Angels and demons, you all come here when you die (...) sleeping an endless, peaceful sleep."

- Cosmic Entity and Castiel

The Empty is a void that existed before God or the Darkness. It is stated that nothing has ever escaped the Empty which serves as an afterlife for angels and demons, where they sleep for eternity.

Background
According to the Cosmic Entity that controls the Empty, the realm existed before even God and the Darkness. Upon death, every angel and demon are sent to the Empty where they sleep for eternity.

Season 11
In Form and Void, hunter Sam Winchester meets the Reaper Billie, who tells Sam about the Empty. Billie states that when the Winchesters die, she will throw them into the Empty so that they can never be resurrected again. Billie notes that Sam will soon go to the Empty due to his Rabid infection. In Red Meat, Dean commits suicide via drug overdose to negotiate with Billie to bring Sam back. Billie refuses, stating that she would never make a deal with Dean even if Sam wasn't dead. "The Empty awaits" Billie announces as she prepares to take Dean to it. However, Dr. Kessler manages to revive Dean and he avoids being sent to the Empty.

Season 13
In Patience, Jack calls out to Castiel, awakening him from the slumber inside the Empty.



In The Big Empty, Castiel then wanders the black void, calling out for anyone as he is followed by a strange being. He is soon greeted by the being revealed to be the Cosmic Entity who takes on Castiel's form to communicate with him. The Entity explains to Castiel what the Empty truly is and is shocked that Castiel is awake as not even God has power over the Empty. The Entity is enraged that Castiel is awake because as long as Castiel is awake, the Entity can't sleep.

The Entity searches through Castiel's memories, much to Castiel's dismay, and finds nothing. Castiel suggests the Entity get rid of him by sending him back to Earth but The entity suggests that it instead throw Castiel so deep into the Empty that he can't bother it anymore. However, Castiel recognizes that the entity is bluffing and that it won't work as the entity would've already done it if it would work. The entity acknowledges that Castiel is right, but refuses to send him back and tries to convince him that he is worthless and has nothing to return to. Castiel refuses to accept this and demands that the Entity send him back to Earth, threatening that he will fight the Entity for eternity if it doesn't release him. Castiel's efforts were ultimately successful and the Entity returned him to life on Earth in order to be able to return to its slumber.

In Tombstone, Castiel tells Sam and Dean that he was sent to the Empty and informs them of his experience in the realm of nothingness. He also explains he was awoke from his slumber by Jack's voice.

Trivia

 * The dark void known as the Empty has possible similarities to Sheol from the Hebrew Bible. Such as Sheol is described as a place of darkness and stillness, where the righteous and unrighteous go after death. This is similar to how angels and demons going to the Empty. Another similarity is Sheol is described as absent or cut off from life and God, similar to God having no power over the Empty.
 * It is unknown if angels and demons from Apocalypse World come to The Empty after their death.
