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.
The Empty is known to Angels and Demons alike to be a supernatural purgatory, but only Reapers (A class of Angel destined to serve the purpose of carrying souls to their final resting place) know in profound definition what happens inside said dimension. It is known to reapers that this serves as the resting place for every deceased Angel or Demon, and that it's completely impossible to escape it.
According to the Cosmic entity that rules over the Empty, before God and The Darkness the only thing that existed was nothing but empty, giving the hint that The Empty is older than the later.
