Cedric sent the Night Stalkers back to where they came from.
The difference is that they're his spies now. He severed their connection to the soul network of the demon race, which was almost the same as them being killed in action.
This so-called 'Soul Network' is something he discovered from reading the Night Stalkers' memories. It's the secret behind their 'Immortality'.
Demons that are killed by humans won't truly die. They will lose their flesh, yes, but so long as their souls remain intact, they will return. Upon their physical death, the souls of demons will be called back to the Soul Network, joining the queue for rebirth. A machine called the Flesh Incubator will be responsible for attaching their souls to a new set of physical bodies, and in there, they will stay until the fusion is over. Once this process was over, they got to walk and live again.
