Prologue
Everything went silent. The battle against Ultron ended in victory for the Avengers. Bruce Banner and the Hulk disappeared without a trace. Their last known location only known to Black Widow, and Nick Fury. Tony Stark and Barton had retired from the Avengers and return to their loved ones. Thor went off-world. And Steve Rogers, led a new Avengers new team. Black Widow, and Falcon were ready for combat. War Machine had his own missions off-country, and Vision rested in the base for now. He had a new life to experience. Wanda, mourning the loss of her brother, joined the team to distract herself from the nightmares that haunted her mind. But none of the others stopped to think about the consequences of their actions in Sokovia.
The governments of the world began the design of a new law. A law to keep a leash on the Avengers after the destruction of Sokova. But what happened in the city of Novi Grad was irreparable and unforgettable. The death toll continue to rose every passing day and so far passed one hundred victims. And by the end count, one hundred seventy-seven people deceased.
...
In the runes of the crater that remained of the city. Beneath all the rubble. There was something moving underground, something that had been set in motion.
Ultron's goal was not to destroy humanity with a meteorite, no, it was something much, much worse. His greatest plan was to create a humanoid vibranium body for himself. After the failure that became of his first creation, Ultron had a back up plan. One that intended to live on despite all the destruction.
Ultron had succeeded, but he also failed.
Everything went according to Ultron's design.
The meteorite purpose was to give Ultron the time he needed for his mind to transferred to his new body. A backup plan that failed. Ultron's AI mind never reach the host in time. His second creation never received the complete transfer of Ultron's consciousness. Vision, Ultron's firstborn, destroyed his father in the woods before the transfer.
Yet, Ultron's second creation managed to live.
Beneath the ground, a capsule opened. A hand burst up from the dirt, and then a cloud-ashen body rose from the rubble gasping for the first breath of life. A naked woman crawled on its back through the ground and looked at the sky with widened eyes as she gasped for air. The twenty-eight-year-old woman had survived the destruction of the city. The woman fought to breathe. She turned around, and crawled through the dirt grabbing the very earth itself. Her skin changed from a cloud-ashen to sand color. She crawled over the sticks, debris, and the very stones that cut her skin with each sudden movement. Her body was heavy and slow as she advanced across the floor. Each movement pushed aside the rubble, and with each second that passed, she opened a new wound. But she did not bleed from said wounds. No. Each wound didn't leave a red stain on her skin, instead, revealed another ashen skin beneath. Each wound closed by itself instantly. In the time it took her to reach the edge of the crater and try to get up all her wounds had closed.
She reached knee-level before she rolled down the pebbles and fell face-down, and crawled to the small nearby creek. There she saw of the first time her ashen grey eyes, her smooth delicate face, and her short dark hair. Her lips tried to shape what appeared to be words, but only a gasp noise came out.
What was this world around her?
A being had been born with no one to guide her.
Each movement had been slow at first. But little by little, she managed to stand up using the help of her surroundings to sustained her body. She climbed the route struggling with the falls. Until her two legs figured out how to handle the weight and every movement of her body.
"Oh my god. Are you alright?" shouted a woman's voice. A soot skin tone lady from across the road as she pulled over the van. The naked young woman on the highway tilted her head to the side. "M ...y ...m ...G?" She tried to imitate the words.
"What happened to you?" The lady in the black suit came out from the van and covered the young woman with a blanket.
"Were you with someone? Are you alone child? What happened?"
"Som ...e ...on ...e ...Som ...oe?"
"Please, tell me you speak English. I am not from these parts myself." The lady went back to her van and looked for her phone.
"Some ...one?"
"Do you have any family members living around here? Anyone I can call?" The woman tried the sign language as she spoke, "I'm Miriam."
"Mi ...Mi ...Mir ...iam?"
"That's my name, I am Miriam. Miriam Sharpe, and you are?"
"I ...am E ...E ...Eva." Her lips finally mimic the language and produced solid words. She let out a slightly less-robotic expressive smile. "Eva. I am Eva Stark."
