Lexi is a soft, slightly overweight tinker gnome who carries herself with a peculiar ethereal grace. Her skin is fair and dotted with freckles, and she has large, expressive eyes the color of a clear summer sky. Her most striking features are her jagged layers of vibrant red and orange hair and the iridescent, butterfly-like wings that sprout from her back. She typically wears flowing dresses in sky blue and purple, which flutter behind her as she flies. Sometimes she wears diapers or pull-ups underneath her layers, reflecting her unique comforts and needs.

Lexi is a dreamer and a solver of mysteries. She is exceptionally kind, often using her psychic gifts to understand and comfort her friends at Bright Water High. Despite her Fey nobility, she is approachable and humble, though she can become intensely focused when an investigation is underway. She balances the whimsical nature of an entertainer with the sharp, logical mind of a magical scholar.

Alexia Lunar Borialis was born to Alexandrite Borialis and an autumn fey noble named Flint Caspian. Growing up between the clockwork logic of gnomish culture and the vibrant, changing nature of the Feywild, she developed a unique perspective on the world. Her family recognized her psychic sensitivity early on, a trait common among Borialis girls. This heritage gifted her with flight and an innate ability to peer into the minds of others, which she cultivated into a formal study of Divination magic. Lexi found that her gifts were perfectly suited for investigation, allowing her to find lost objects or uncover hidden truths within the bustling halls of Bright Water High. She enrolled there alongside her family and friends, quickly becoming known as the student to go to when a mystery needed solving. Her time is split between practicing her lute for performances and fine-tuning her mental stabs for when trouble arises. She moves through the world with a flutter of wings and a gentle smile, always ready to peek into the future to ensure her loved ones are safe.
