I had been called an enforcer of the Deadly Alliance. I preferred the term "ambassador". It was my duty to impose the will of Quan Chi and Shang Tsung upon the denizens of Outworld. But the sorcerers' rule was short-lived and I found myself leaderless, longing to return to my birthplace in Edenia. When Baraka caught up with me, he gave me a choice: Serve his new lord of Outworld ? or die. I have lived for thousands of years because I make the right decisions. I pledged my service to the Dragon King.
Onaga was aware of Shao Kahn's invasion of Edenia so many years ago. Apparently the Dragon King had been watching Shao Kahn from beyond death. Whatever the late emperor had been attempting, Onaga was determined to complete it. He was looking for lost information, ancient spells that would fuse the Elder Gods' six Kamidogu into one and therefore make it possible for him to wield their combined might. I brought him to Edenia, where I believed that information still existed.

In Edenia, Tanya had located the ancient texts that described the process by which to fuse the Kamidogu into one. With this information, Onaga was able to create the One Kamidogu - a tool of unspeakable power.
As the Dragon King was distracted, reveling in his victory, Tanya seized the opportunity to snatch the Kamidogu from him, thereby obtaining god-like power. She destroyed the Dragon King and became Ultimate Overlord of the realms.
