"They need to understand the prior Multiverse, how it all ended, and most important, you have to explain the importance of The Glass that exists in all renditions of the Universe whether you draw on your concurrent versioning system metaphor for the Multiverse, and honestly that's my favorite, because it works with your theory that the Earth is just a massive new data fountain used to regulate the expansion rate of the Multiverse. You also have to explain Kay better. She's your "best girl" and deservedly so. Kay stood on a mountain. It's like you forgot how damn important that was. Kay gave up everything for Jasher's vision based on a promise. You need to talk about that."
1) The Glass
Was a feature built into a prototype version of the Multiverse Shell that Jasher had created 17+ billion years ago. It was complete hubris. He wanted to be able to sell people a tailored Multiverse that could still be linked to the overall network that had a true physical window back into the parent Universe when you were inside it. So the The Glass had never actually been implemented in any Multiverse prior. It was a view port into the Donor Universe. A fantastical feat of time engineering only Jasher could have accomplished as the original designer of the Multiverse Shell platform.
What that means for folks that live in the -3233994677994321233 version of our Universe (The Famous Food Universe) that Jasher loves to death is, it's the ONLY incarnation of the 30 billion years that has The Glass. The rest were spared this abomination. The Glass shows Jasher at the moment of his physical death. It's a million light year wide portal to the prior Universe. The one that spawned our Multiverse. The coldest part of our Universe is on purpose. Jasher made it damn near impossible to reach The Glass. But if you do make it, you'll see what appears to be a huge angry God that hates you glowing in green. But what you are really seeing is Jasher splayed out over the last Multiverse as his entire Universe dies. He's literally sacrificing his body to protect the last Multiverse as he's being burned alive from the outside in. Jasher's last moments consisted of him trying to not feel the pain and preparing for full transfer to our Universe. You see him as the flames penetrate the back of his skull and start boiling his brain. So Jasher in The Glass looks like some huge monster and not some protector.
2) Kay Stood On A Mountain
Kay is Jasher's greatest love. After Jasher died protecting the Multiverse Shell housing our broken Universe, he drifted for a solid billion+ years almost braindead. The system itself resurrected Jasher's brain as a function of it's existence. The system needs a Sysadmin. And that's why Jasher isn't completely sure if he's real or not. He's a byproduct of a system that needed a manager, and had an almost completed personality transfer as its best target to use to create a Master Sysadmin for itself.
That being said... as the reader, you don't know that Jasher is complete. He is himself from 17 billion years ago. He doesn't know either. He's just hopeful his full brain survived, and he's "that guy" that's doing everything. But he can't know ever because of dimensional mechanics. So Jasher will always fear he's just some process. The bright side? That has kept him beyond humble, and the main reason he didn't just give up and destroy everything from the getgo.
The main reason Jasher didn't just decide to die, in a pit of total despair, 15 billion years ago is because one brave woman gave up everything to save us all. And he fell in love with her, and she was named Kay. And that's almost all I can say about that.
What I can say is the portion of space that was created by the explosion of a Wolf-Rayet star that made our existence possible 13 billion years later was the direct result of...
"Look. I have to make this your decision. I'm totally temporal. I at least understand that much. And despite how much it's hurting the absolute fuck out of my head right now, I need to obliterate your system and your culture to make sure one of these massive data gobbling monstronsities is somewhere else in 13 billion years. I hate this decision Kay. You stood on a mountain. You petitioned me. You begged me to play fair. But I can't."
Kay trembled. Not only had she suffered insane hypothermia, the nerve damage from the repeated particle bombardments had virtually ensured her swift death. She was going to die. She knew it. But the worst part is her brain was being eaten alive by the constantly appearing and reappearing particle pairs this close to the singularity she should have never approached. Kay was going to die. This powerful being could not help her. But it might be able to compromise.
I really do.
4) It's going to be hard to write around what I can talk about because they LOVE Kay. I can sell a story instantly if I make it based on Kay. She's an amazing character. The premise is that she gave up her entire race and culture to a Black Hole that gobbled them up because she's betting on Jasher saving us all. It's a good bet. He's going to do it.
Overall the story of Jasher was me taking every existing creation myth from every culture I could find, and making my own creation myth that fits better than all of them, but updated for 1990. I'm taking that work and updating it for 2020. That's what Jasher is. Me proving I could write a more compelling creation myth that incorporated all of them.
