Eastern Sage

Sage from the East, Beast King of the West, Northern Shaman, The Great Gilgamesh, and lastly his friend The Warrior Enkidu.

These five people were known as the first generation of Earth acolytes.

Emery honestly thought that everyone of the five had died except for Gilgamesh as what the latter stipulated before. 

But then, he did learn from the Abbot that the one known as the Eastern Sage, Emperor of Xia Dynasty was the person who gathered and trained the Abbot and the other second generation Earth acolytes.

"But Lord Izta, I heard from the Abbot that the Eastern Sage went missing mysteriously during the huge war that occurred 1,000 years ago."

Emery could see the surprise on the man's face when the latter heard his words.

The man let out a deep sigh before saying, "So, you've even heard of that huh..? Then, you should know that it is the work of the Nephilim, again."
