Bronwyn was born in Hommlett, the only child of High Elf weapons merchant Leon Goldleaf and Wood Elf artist Morgan Goldleaf. She also, through her father, is the granddaughter of famous Imperial War-era High Elf poet and peace protestor Owyn Goldleaf. Her mother died giving birth to her, causing Leon to blame her death on their daughter and abuse her both psychologically and physically, and this only became more pronounced as she grew older and he found out about her homosexuality.
Unable to take the abuse any longer, she ran away from home and found herself taken in by a Grand Order of Wizards librarian, who instilled her love of magic in her and helped her to heal the scars her father had caused on her mind (though she did keep in touch with her paternal grandmother Imelda, who did not share the same conservative leanings as her son). Eventually she joined the Order herself, beginning as her adoptive father's library assistant and eventually working her way up to a Journeyman. During this time she also encountered Willow Byrne, her future wife. As a student, she excelled academically and studied Thaumolinguistics, eventually graduating with honours and earning a Doctorate in the subject.
Upon her biological father's death, she became the sole beneficiary of her parents' estate due to his having no other living relatives and the reasons for his removal of her from his will being deemed unlawful by the Imperial Courts, and proceeded to either destroy or sell nearly all of her father's assets as well as using her newfound wealth to sell all of her mother's works to museums so she could posthumously get the recognition she deserved, with one exception - a self-portrait which she kept to remember the mother she never knew.
She and Willow married in The Imperial City of Gor’Raj’Ka in the grounds of Willow's childhood home of Glasbháin Grange, and their wedding was officiated (and paid for) by Willow's mother Saskia. They currently reside in a large cottage in Hommlett, the former home of Bronwyn's paternal grandparents that was specifically given to her by her grandmother. She works at the Grand Order Training Tower, where she is the Professor of Thaumolinguistics and also teaches History of Magic.
