As Aldrich was faced with four beings in the same realm as him, he actually weighed his options as he came to the truth that he had more than a 60% chance of winning if he actually faced all these beings at once.
But he really did not like this percentage, as it involved something that was extremely important to him! It was his life's work, and he did not wish to risk it for a 60% chance!
It was the reason why he initiated the Last War, with the prize actually being nearly within his grasp as when he achieved it, he would have a 100% assurance of winning against any beings in the Novus Galaxy, no matter what power they held.
He was so close, that it seemed just a few days or weeks was all he needed!
