It's been a while since I posted an omake, let's correct that.
This was inspired by a similar omake on another story, and I realized it could work here too.

The Great Creator
"Alright, what happened?" I sighed as I looked over the devastation before me.
I had been in the middle of a sparring match with Tybalt when I received an urgent message from my duplicates to come to Survey's scrying room. Once I arrived, I found the room a mess, with both of my duplicates fixing the damage.
Fortunately, the room was so heavily warded, no one outside probably heard or felt anything.
"Well" one of my duplicates started. "We decided to upgrade Survey's mirror."
I looked at the dozens of new mirrors lining the walls of the room. "I understand that, but how does that explain the damage?" I asked.
"The new mirrors with Craftsmen of the Gods can give new properties." Explained the second duplicate. "We were building prototypes to see what was possible."
I motioned for him to continue.
"Alright, the mirrors have additional properties, but the ones here all have different properties. It seems that Master Craftsman, Daedalus' Student, and Craftsmen of the Gods all synergize pretty well. We were just starting to test the mirrors and used one that showed images of the past."
I blinked. "How does that cause this mess?"
"Well, it turns out that under the right circumstances, relatively small amounts of energy can pass through the mirror." the second duplicate continued.
"Now that we know that can happen, we can build the mirror so it doesn't happen" Added the first duplicate.
"OK, I think I get it, you observed something in the past and energy passed through the mirror to create this mess." I said. "What were you looking at?"
"Well, as the objective was to determine the limits of the mirror, I attempted to look as far into the past as I could." Survey said.
"Turns out the mirror can look as far into the past as possible." added my second duplicate.
I blinked at the implications. "Wait, you observed the big bang?" I asked.
"Seems like it." Replied my first duplicate, as he transferred the experience of the event.
I felt a headache coming on. "Alright, I guess that explains that. Anything else I should know?"
"Well, Survey might count as the creator deity of the multiverse." My second duplicate quipped.
"What?" I asked.
"Well, according to our calculations, the big bang extended through multiple, possibly all of the universes in existence." Said my first duplicate. "It seems that it would have generated enough matter and antimatter in the proper positions to cancel itself out, but the small amount of matter and antimatter that leaked through the mirror created a chain reaction that destabilized the equilibrium. That resulted in some universes having an abundance of matter and some having an abundance of antimatter, the pattern that we see continue to play out today."
I stared blankly at my duplicates and Survey as I reviewed the data provided. After a deep breath, I responded.
"Nope, this is going with the demigod genetics, Satan summoning, and soul use as shit I'm not going to deal with." I stated as I walked out the room, trying to put the encounter out of my mind.
By which story was this inspired?
Because the idea of someone accidentally creating the Big Bang via a Time Portal sounds exactly like a Story Omake I read over on the Sister Forum Questionable Questings.
