 The Heavenly Realm is home to many powerful gods of various mythologies and legends like the Jade Emperor, Michael the Archangel, Hercules... At the dawn of time, humans, demons and gods lived together on Earth.The gods allowed the weak humans to borrow their powers, creating the "Borrowed Power" system (or "Charyeok" in Korean) so they could defend themselves against the demons who wanted to rule over them.Shortly after the demon defeat, the gods split up the humans, demons and gods among the three Realms.
