"Well first off. Do you see the Hindu priesthood throwing magic WMDs around today?" I asked him.

"No..."

"Second off. They self-destructed because of... to summarize... 'Brahmastra', 'Indraastra', 'Suryaastra', 'Agniyastra, Brahmashirsha Astra.

"All you did was add 'Astra' to some pagan gods' names," the technically an adult said.

"First off, Agniyastra," I declared as I closed my hands together as if to pray. And as I separated them, a lance-like arrow of Transcendent Divine Soulflame manifested in my between them, the flame prismatic like the reflection of a diamond and emanating golden light. It's radiance was almighty, yet it did not hurt our eyes.

"Agni, the Lord of Flames, the Burning One. Astra, means arrow. And this arrow," I pointed at the Transcendent Magic right in front of me.

They are wide-eyed. Good, they can sense, if barely, it's majestic strength.

"Has more power in it than the combined nuclear arsenal of America and Russia. And it is made entirely out of its namesake."

"And how many of them were thrown?" The first one to talk, Ibrahim if the others thoughts were correct, asked.

"Only 1 per 1000 Astras detonated. The rest were negated by each other. But over a thousand were successfully used. And it reset human history."

"C-c-casualities?"

"1.8 billion in Ancient India alone. Those are immediate casualities in an eighteen day war. Probably higher once you take in the nuclear winter effect."

"..."

"So... over the course of this history lesson. I realized something," I began.

Ibrahim raised his eyebrow.

"I objectively cannot justify showing you all mercy."

They remained silent.

"First off, your entire bloodline has been a menace to humanity, not just me."

"Second off, not only were you menaces. Your ancestors in particular actively decried inventors as heretics rebelling against whatever God(s)^TM your family believed in. Congratulations on killing the inventor of modern medicine fourteen times over. Well done."

"Finally, while the Catholic Church has no idea of magics actual existence, you do! And you did way worse proportionally on a per capita basis."

They were not silent. They were trying to scream. But I was not letting them.

"Add effect Reincarnation Cessation to Agniyastra."

There was some tossing, some light, and then a man floated in silence, a spear of beautiful flames in hand.
