It was always dark in Hell. The walls were covered in blood, and bits of flesh. There were screams of terror, flashes of lightning and smoke. There were no lights, as they would flicker when the tormentors walked by, causing a wave of annoyance throughout the occupants of the inferno.
Cas had long since given up on fighting. A man would always ask him if he wanted to torture or be tortured, and after years of enduring the worst kinds of pain, he finally chose to save himself. It was almost worse to see the anguish he inflicted upon others. The face they would make as he broke them, shattered their souls; but then he remembered when he felt that way, and it suddenly didn't hurt anymore.
Sometimes, he would wish that his brother would sell his soul to save Cas, but when he thought about his brother going through the same pain he was feeling, the thought vanished almost as quickly as it came. He wished someone would rescue him, but deep down he knew it was a naive and childish dream. He was stuck in Hell, and there was no one to save him.
At one point during his fortieth year, nearing his fiftieth, Cas saw a light. It was bright, almost tricking him into thinking it was the sun, but after decades in Hell, he knew better. As the light grew brighter, Cas realized this wasn't something he was imagining. He wondered briefly if this was a new way the demons had decided to torture him-maybe they wanted to give him false hope of escaping. Closing his eyes, and not for the first time, he desperately wished the torture would end, and that he would be free.
The light shined brighter, if that were even possible, and Cas went to shield his eyes, only to realize that the light shined through the barrier he attempted to make. As hands gripped his shoulders he released a whimper. He went quiet as the person holding him shushed him. Cas risked a glance at the one supporting him and saw him open his mouth. A piercing noise filled the area causing Cas to cover his ears, as if doing that would stop the noise completely. Soon the noise was too much and he surrendered to the darkness.
