Denwen

The ancient serpent god was known from the Old kingdom as the "fiery one". He was renowned for his dragon like powers that enabled him to breathe fire, it is said that he was about to destroy all the deities in the pantheon in a fiery conflagration when, according to the Pyramid texts, the dead pharaoh stopped him from doing so. Considered by Egyptians as the symbol of the final threat, of absolute evil, they wisely kept their distance from him.
