The Child Of The Sages' Plan.

Anyone that succeeds in acquiring immortality has strived for it with hard work or acquired it through privilege and talent. No origin God is a slouch. They are all talented in their own way. But apparently, that isn't enough for the creator of the Void universe. 

The void universe continues to pit these talented people against each other. They are immortal so there's no permanent loss. They can always be set up against each other and used to sharpen each other again and again until something unknown happens. 

"But the universe is ending soon. Whatever the creator wants to achieve had better occur soon or we the world gods will tear the universe asunder." The sage thought to himself in glee.
