Jade Dragon-God Emperor

The Jade Dragon-God Emperor was the Emperor of the Jade Dragon Empire and supposedly the most powerful cultivator in the world at the time of the Calamity.

History
The Jade Dragon-God Emperor played an enormous role in replling the invasion of foreign beings, with the Grand Elder of the Main Sect of the Heavenly Lightning Sect citing him as one of the reasons the world still exists. However, details about him after the Calamity are scarce, and no one really knows what happened to him afterwards.

Strength
The Jade Dragon-God Emperor was supposedly the most powerful cultivator in the world at the time of the Calamity. Whether or not this implies that he was the ruler of the world at the time is unknown.

Talent
Aside from his immense strength, the Jade Dragon-God Emperor was the greatest talent in the history of the world. Before John Fenix climbed all 20 steps and became the current Rank #1, the Jade Dragon-Gode Emperor climbed 19 steps on the Divine Talent Steps, which made him the previous Rank #1 amongst the ten names in the top section of the tablet that records the results of the Divine Talent Steps.
