1 year after the birth of Steven universe

The cluster woke up prematurely, causing series of cataclysmic events. Volcanic eruptions covered entire countries, killing millions of people in the process but it only covered the western part of Europe. The entirety of Eastern Europe and Asia sank in the ocean due to the Earth's crust destroyed by the cluster manifesting its physical form. Africa suffered the most out of all damaged areas, torn apart by multiple if not the strongest earthquakes humanity had ever witnessed. Oddly enough, the cluster returned to its dormant state and it is unknown if it will emerge and destroy the earth, wiping out what remains of humanity.

1 month after the cataclysmic events

Beach city was in chaos. The effect of the disaster were too much for the citizens of the small town, now every one cared only about themselves, will they find food? Will they find water to drink? No one knows what lies ahead except for the Crystal gems. They knew what was coming and readied themselves for this, cradling a new life is sure a hard job in a doomed world.

"Peridot, Pearl, is it ready?" Asked garnet

"It's ready alright, the thing is that we have some bad news," they both said.

"Well spit it out, we haven't got all day long" A voice said, it was loud and a bit harsh and they knew whom it belonged, it belonged to Jasper. The ex-home world gem was not happy at all. Those two sure took their time modifying the escape pod for dimensional jump, she was no scientist but they think too much and probably will take more which is why she is so damn pissed.

"First, we haven't found an energy source strong enough to power up the pod and the warp pad"

"AAAnnd?" The quartz soldier added

"The cluster will emerge next week"

"WHAT DID YOU JUST SAY?" She screamed "THEN MOVE YOUR ASSES AND DO SOMETHING ABOUT GOD DAMN IT" The quartz soldier added.

"I can't believe that I'm saying this but the only thing we can do now is harvesting the corrupted gems energy." Said Garnet

"And I can't believe you saying that" The shocked Pearl said.

"I know pearl, but what choice do we have. We Promised Rose we would take care of Steven no matter what and we are going to keep that promise."

6 days later

The ground shook violently, the cluster is finally awake and in the process of manifesting itself. No place is safe to hide; the earth is at its final moments as the cluster tore through it. The crystal gems panicked and were doing their best to ready the escape pod. With every moment, passing the ground shook even more violently, making the gems even more panicked then before. Jasper out all of them, feared for the one-year-old infant's life more than about her own but now that everything is ready and Steven is within the pod. Everyone said their goodbyes except for Jasper; she wanted to be the last to see the boy before they send him to another world, and as she leaned to give him a kiss she felt a sharp sensation, pain tore through her form, she turned around to see who did and it was garnet.

"Why?" She asked, barely holding herself seeing the fusion crying.

"This is for you and Steven, make sure you take care of him." Moreover, with those words Jasper was poofed leaving Garnet thrusting Rose's into thin air. Garnet placed the fallen gem within a bubble, placed her between the hands of the baby and placing his mother sword beside him, she closed the pod signaling for pearl to launch the pod. With that, the escape pod vanished in a blinding light, leaving the gem waiting for the doom.
