Prophets
Chuck Shurley is a Prophet of the Lord. He appears as a human writer who has published numerous novels that record every detail about the lives of Sam and Dean Winchester. Each novel recounts one episode of the TV show. He was inspired to write these by visions he kept having--visions that left him with headaches, which led him to drink liquor. However, as his visions compelled him. He did not know that Sam and Dean were real until they found out about the novels and sought him out, angrily confronting him at his rundown shack where he lived. Also, because Chuck is a prophet, the archangel Raphael, who demonstrates powers strong enough to scare even Lilith, is his guardian and protects him at all costs. Chuck's books contain some details that even Sam and Dean do not know.
Then theres Kevin, the other Prophet of the Lord. He helps Sam and Dean translate the tablet. Crowley wants Kevin dead which causes Kevin to go crazy. Kevin then recovers and continues to help. One day Dean comes home and sees Kevin on the fllor, dead. Gadreel killed him and took the tablet.
