They are a fan made set of emeralds that I created. They are called Discard Emeralds. They were created by scientists in an attempt to try to control nature, but the experiment went haywire and resulted in the birth of them. They can control many different elements of nature, too. Red controls Fire. Blue controls Water. Brown controls Earth. Green controls grass, trees, and other vegetation. Light Blue controls Ice. Gray controls Wind. And Yellow controls Electricity. Whoever uses these can control all seven of these elements. And along with their ability to make someone take a glimpse into the future at random periods of time, they are a major target for villains. However, they remain hidden from living beings in the outside world very well, so they are hardly ever seen, and almost impossible to find.
