Demon

The Demon is an evil, mysterious being, responsible for Castle Rock's doom. He struck a deal with King Bartholomeus promising him an eternal life. 
== Appearance ==
The Demon is often depicted as a long green serpent with sharp, white horns on it's head and long fangs in it's mouth. It is speculated that the Demon can shapeshift due to the different depictions of it.
== History ==
When King grew old, he became impatient in his search for immortality. He decided to turn to the Demon for help in achieving his dream. The Demon offered him a contract promising eternal life. When the KIng signed it, he doomed his kingdom, creating the eternal winter that covered everything in thick snow. He gained immortality, his soul forever bound to the castle, even long after everyone close to him died.
== Speculation ==
Some people believe that upon signing the contract, Castle Rock and everything surrounding it was transported to Antarctica, causing the sudden winter. This theory suggests that the keep wasn't there originally.
