Warcraft Original Black Instrument

In the endless chaos, God created this world with a crystal that contained all power. Following this, this crystal containing powerful power was scattered all over the world - gradually, a substance called magic stone appeared in this world. Magic stones are randomly generated from all things, such as water, mountains, mines, and even animals or people... They contain huge energy. Only people who have a connection with magic stones can use magic stones. They are called Summoners.
