The Marshall family is the first and only family on Midgard with the gift of immortality. This ability was granted by a powerful witch named Evthys de Clare, who became Evthys Marshall after marrying Wyatt Marshall. Devastated by the loss of her daughter, Ellaire Marshall, Evthys cast an immortality spell on her family. Her two sons, Theron and Kieran Marshall, have continued to live on, until the present day.
Over the centuries of his existence, Kieran had been responsible for countless deaths-thousands, perhaps even millions by now. Ruthless and quick to anger, he never hesitated to kill, especially those who harmed witches or innocent women. Following the Salem witch trials, Kieran eliminated everyone involved, disguising their deaths as accidents. But his brother knew the truth.
Theron was the more composed of the two brothers, having greater mastery over his powers than his younger brother. He eventually started a family, which brings us to his present-day descendant, Antonia Katherina Marshall. Unlike her predecessors, Antonia possesses unique powers as the family's first telepath, with the additional ability to manipulate time and foresee the future.
Her life was filled with hardships and repeated trauma, but things began to turn around once she was adopted. After being adopted by Tony Stark, Antonia's life took a turn for the better. The young girl, once known for her blonde hair and striking purple eyes, chose to dye her hair brown, wanting to hide the fact that she was adopted.
She soon started attending Xavier's School for Gifted Youngsters, a unique place designed for children with superpowers like hers. But one night, everything changed when her visions returned... She knows she must act, but can she? Can she save the ones she loves, or will she be consumed by darkness?
In 1995 after a one night stand with a woman supposedly called Katherine Ravens, Tony Stark becomes a father to a daughter that he names Evelyn Maria Stark. As she gets older, it's obvious that she gets a lot from her father but along the way she finds out that her mother gave her something pretty big, powerful abilities.
After being assaulted and tested on by the Ten Rings those abilities are brought forth, she leaves Afghanistan scarred in more ways than one. When she find out about her abilities she fears that she will be a danger to the ones she loves but soon begins to learn how to control them and finds herself thinking that maybe she can become a Hero, like the ones from stories.
Along the way of becoming a Hero and finding herself, she is confronted with the facts that she was born with her abilities and that she isn't fully of Earth. On her journey she finds the mother that abandoned her and finds a family in her teammates, The Avengers, though her feelings run quite a bit deeper for a certain someone, that someone being the one and only Steven Rogers A.K.A: Captain America, A.K.A The First Avenger.
Follow Evelyn as she becomes Elementa and eventually finds love with The First Avenger.
