Shayol Gul

In the Wheel of Time fantasy novel series, Shayol Ghul is a mountain beyond the Great Blight in the north of the known world. It is the place in the physical world to which the Dark One's prison seems closest. The distance to the prison and the Bore is really no shorter than anywhere else, but the Pattern is thinner there, enabling The Dark One to exert far greater control over the mountain and the surrounding area than other places in the physical world, and his high-ranking followers such as the Chosen travel there to commune with him. The Prophecies of th Dragon state that TarmoGaidon, the Last Battle, will take place in part at Shayol Ghul. Deep within the depths of Shayol Ghul, there is believed to be a place known as the Pit of Doom in which the Dark One resides, it is often heard of in stories and is occasionally used in some sayings implying that they'd much rather be there than where they currently were.
