Evelynn has long, curly copper-red hair (natural) and hazel-green eyes. She has pale skin, freckles and rosy cheeks. She has a button nose, long pale lashes, and two ear piercings in each lobe. Evelynn has a slender body shape and is just under average height, with a heart shaped face.

Evelynn's personality type is INTJ. As a young child, a test revealed that she has an extremely high IQ. She is both incredibly logical, but also very creative. She has a strong sense of right or wrong, and often values others' needs before her own. Evelynn values giving wise insight and helping others, and is also a people pleaser. She is prone to anxiety and doesn't trust easily, but is very loyal when she opens up to people.

Evelynn grew up in a loving family with her father, mother, and no siblings. She went to private school, but didn't make any friends, as all the kids thought she was weird. While she had no friends, her aunts, uncles and cousins often visited, and she had a pet ginger tabby called Athena. Evelynn grew up in a Christian family, and went to Church every weekend.

When Evelynn was younger, she didn't have a great control of her emotions. She would get angry very easily, and would stay provoked for a long while. When she was 6 years old, she became quite irritated when her older cousin (Lara) wouldn't share her toys. In her anger, Evelynn unknowingly caused painful boils to burst all over Lara's skin. Evelynn didn't immediately realise what she'd done, but when she did realise what her actions had caused, she was mortified. From then on, Evelynn kept a careful gage on not only her temper, but also all her other emotions. This is one of the core reasons she struggled to open up to people.
