The daughter of Wood Elf fashion designer, investor and former detective Saskia Byrne and Dark Elf travelling bard Faulkner Chulainn, Willow grew up in the lap of luxury in The Imperial City of Gor’Raj’Ka in her family's huge manor house, Glasbháin Grange. She grew up doted on by her mother and her grandfather as her mother's only child, but never met her father until she was already an adult. Her godfather was her mother's close friend, the late Grand Order alchemist and private detective Set Amenhasensahib.
At a young age, she began training to join the Grand Order, much to her mother's delight, and having grown up with a taste for alchemy from reading books from the Amenhasensahib house and asking questions to Set's Unknown Unknown. She was a hard worker, though not exactly the best student due to her boisterous and slightly hyperactive personality, and she eventually graduated with a major in History of Magic and a minor in Alchemy. It is also during this period that she met her future wife Bronwyn Goldleaf, and would finally meet and form a bond with her father Faulkner after decades of his absence from her life.
After graduating, she and Bronwyn moved in with her mother for a short while, and were married in a quiet ceremony at her childhood home of Glasbhain Grange which was officiated by her mother. The pair soon moved back to The Grand City of Mor'Koc however, and now reside in a large cottage in the woods outside Hommlett formerly belonging to Bronwyn's grandfather. She teaches at the Grand Order Training Tower, teaching Alchemy and History of Magic as well as General History, and also is one of the Grand Order's most skilled archeologists, most notably being one of the highest ranking members of the dig at Veg Darul led by peer and longtime friend Hathor Nepthys Ivarsdottir.
