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 Thaumic Engineering and a minor in Alchemy. It is also during this period that she met Bronwyn Goldleaf, who she would begin a romantic relationship with and eventually marry in a quiet ceremony in the grounds of Glasbhain Grange.
She soon moved back to The Grand City of Mor'Koc and now resides in a large cottage in the woods outside Hommlett formerly belonging to Bronwyn's grandmother. She teaches at the Grand Order Training Tower, teaching Alchemy and Thaumic Engineering, and also assists with archeological digs of Dwarf sites due to her scholarly knowledge of Dwarven engineering.
