Five thousand years ago, the emperors Yan and Huang sought Yinglong’s help to defeat Chiyou. Using his own dragon teeth, Yinglong forged ten Ink Dragon Pestles. But their power was so overwhelming that anyone who used them directly would die, so he crafted three Ink Dragon Inkstones, [Pine], [Bamboo], and [Plum], from his own claws to lessen the side effects.
