So far, things had gone according to Chiron's plan.
First was the issue with Ralph and climbing the mountain that happened to have Chiron's sword waiting for him.
Secondly, was the battle.
Chiron had to ensure that the battle looked as visually convincing as possible. He even went so far as to pump some aura energy into the sword that helped increase Ralph's power.
The reason Chiron had done this was because he needed to recreate as close as possible a resemblance of what happened to Mani.
After the event that Mani had suffered, he had become mostly a shut-in kind of a person and this was Chiron's attempt at opening his heart.
The reason was because misery loves company. Even better, he was able to provide Mani with the possibility of seeing himself in Chiron.
Therefore, he granted himself the illusion of the possible peace and happiness he would have achieved if he had not lost his own wife.
That was for Mani.
