The Unknown: An Avengers Fan-Fic

After the Avengers saved the world from Loki, they made sure he would be imprisoned forever. However, no one prepared for her.
Her name is Rayne Forewick, and she knows things. Things that could destroy the world. She is a genius, a magic user, and has enough emotional baggage to bury her alive. People always seem to end up dead around her. Her first move is breaking Loki out of jail, but why?

After the Avengers saved the world from Loki, they found something that would change their lives.
That something's name is Ekaterina Petrolia, and she can't remember anything but brief flashes of her life before she was locked in a coffin for a century and a half. She is a shadow, quiet, and beautiful. Her mind is shattered when she wakes, but parts of her extremely intelligent mind still holds fragments of memories, slowly piecing together her old life that might be better off forgotten.

The two very different girls share a remarkably similar past; both were abandoned at birth, both were raised to believe their adoptive parents were their own...sound like anyone else's story?
That's right; Loki shares the same story as them, and Thor has some of their traits. The four of them, along with the rest of the Avengers, spark separate journeys through the past and struggle to remain true to themselves as their journey brings secrets, memories and blood to light.
Only one thing is certain: lies are the foundation of the new rule.
