This realm was situated somewhere between hell and heaven, and the people working for this facility weren't normal humans. Just like the Headmaster.
Richard had a very faint knowledge of this place given there wasn't much mention of the Endless Hold in the book. It was said that this place established the deities to keep the criminals who have committed grave sins alive long enough to realise their mistakes, and once they did, it was said that their souls gained enlightenment.
Well, Richard was not going there to find this enlightenment.
"Although I don't need to tell you this, don't trust a single person inside there. All of them are just trying to find a way to escape and you can very well be a reason for their protest if you tell them about your situation."
Richard nodded casually as he remained blind under the sac mask, currently draped over his face. Only Marcus knew how to get there, and naturally, he couldn't have let Richard know about it too.
