Echidna's Authority.
Har Jahar canceled the effects of the monster-controlling artifact after its brief use. Clearly, his intent was only to use it as a deterrent here.
"We need to stay together on one page for Echidna's prosperity. The Oni festival would proceed as per our customs with no changes whatsoever."
Har Jahar said in a deep voice. However, he also knew that the iron fist was only so effective. It had its limits. Plus, the sacrifices only worked best when there were genuine feelings attached to them. Har Jahar needed the monsters to take part in the process willingly.
Therefore, only deterrence won't be effective. To make the tribe leaders and their tribes submissive to his authority and cause, he had to adapt a carrot-and-stick strategy.
Therefore, he looked around before calling someone who seemed to be absent from the crowd.
"Kirin!
My child. Show yourself."
