Shin Nong

The God of Agriculture and the previous Emperor of the Gods, as the most powerful god. He loves humans and gods equally, which eventually resulted in Hunwon gathering divinities opposed to Shin Nong and overthrowing him. Once Mui's power over water emerged, Shin Nong granted him the title "Habaek" as the God of Water. However, since Shin Nong's own affinity is toward fire, he and his allies retreated to the Moon Palace, where as gods possessing the power of fire, they are strongest. When Hoo-ye attempts to take Soah, he reveals himself and lets Hoo-ye leave the Lunar palace. He tells Habaek he never intended to meet him in the first place, and is too weak to fight against Hunwon now. He and the current emperor are brothers, but their very natures are opposite and it has been foretold that they will destroy each other. (Source: Wikipedia)
