No Escape.

The first sage tried to use the aspect of Probability to worm his way out of it. He was looking for that slim chance of survival. But Entropy and Chaos were scrambling his perception and luck. Besides, Aeternus had the aspect of Probability too, and he was also much stronger than the first sage. 

The fight was so violent that the continent within the first sage's world was cracking apart despite how strong it was. The living beings in the world were dying in droves. Black chaos energy was submerging and tainting everything. It was truly an apocalypse. 

What's worse is that the first sage couldn't admit defeat and give up his world. He couldn't leave it because, for some reason, Legion-3 had adhered to him like a world ender.
