Hi, I am looking for an old fic that I believe was on fanfiction.net. Sam was at Stanford and something happened causing him to be trapped in some sort of well like location, injured with no food and no hope. Meanwhile Dean is on some sort of ritual hunt that John had gone on. He ends up locating the creature he needs to and receives some sort of special ability due to his actions. Somehow he figures out that Sam is in trouble and he saves him. That is all that I can remember about this fic so please help.
