Born as a 22-year old muscular half human, half spider hybrid, Winona has been a social outcast all of her life. 

She was left behind by her parents when she was a baby on an old lady's doorstep. 

Naturally, when the old lady discovers the her, she is mortified by the her rather disturbing arachnoid appearance at first glance, but soon warms up to the strange girl when she realizes the babe means no harm, becoming her surrogate mother.The old lady makes it her sworn duty to protect this child from the rest of the world.

As the years go by, Winona and the old lady grow a special bond with one another. But as Winona grows up, she yearns to have a life of her own outside of her mother's house. Her mother forbids it, however, knowing the outside world would be unkind to her daughter, reviling her as a horrible monster. Winona becomes restless and upset about her constant isolation, but gradually becomes more accepting of it over time, realizing she will never be seen as a normal girl.

By the time Winona reached her teenage years, the old lady had grown very old. When she passed away, Winona was devastated to lose both her mother and her only friend. From that point on, she was left heart-broken and all alone.

As time went on, the house Winona resided in became the home of a small clutter of spiders in the upstairs attic. To cope with her growing sense of loneliness, Winona became well associated with the spiders in the attic to the point where she began to live among them on a regular basis, spending a majority of her time in the attic.

When Winona was a little girl, whenever a spider was loose in the house, her mother always made sure to let them back outside and to never, EVER squash them, so that her daughter wouldn't be traumatized or have nightmares of being squashed herself. She had nothing but sympathy for such small creatures so similar to her.
