C is for Cinnabar, or, Immortality is not always good for your health

Cinnabar is a mineral of a strong signature red hue that produces the pigment called vermilion. The word cinnabar allegedly comes from the Persian word for "dragon's blood."
I have already mentioned one of the Four Symbols in Chinese mythology, the Azure Dragon of the East. Well, the Vermilion Bird of the South is also one of them, and is fabled to live in a cinnabar cave somewhere in the South
