𝓔 ᴀ ʀ ʟ ʏ ʟ ɪ ꜰ ᴇ | Luna Katherine was born on the 11th of November in 2013 to Jude Wailey and Nataly Wailey-Blair. Jude is a deep sea pressure diver, while Nataly is a very skilled apothecary who runs her own apothecary shop in the small village of Dallas, Scotland. LK has three older siblings (Logan, age 19, born December 3rd 2005; Finlay, age 15, born September 19th 2010; Aisling, age 13, born July 31 2011) and one younger half-sister (Alba, age 6, born March 14th 2019). Alba is Luna-Katherine's half sister due to her mother having an experience with s3xual assault while Jude was away at work. Despite her unfortunate circumstance of conception, Alba is still dearly loved and cherished by the entire family.

Growing up, Luna-Katherine was not a fan of social interaction. She excelled in her coursework in school but had few friends (much to her own pleasure), preferring to spend her time in her mother's apothecary shop; this has allowed for her to develop profound skills in chemistry, cooking, apothecary work, and organization, among other skills. Often, Nataly will rely upon both Luna-Katherine and Finlay to assist her at her workplace, something that Luna-Katherine takes great pride in.

𝓕 ɪ ʀ ꜱ ᴛ ɪ ɴ ꜱ ᴛ ᴀ ɴ ᴄ ᴇ ᴏ ꜰ ᴍ ᴀ ɢ ɪ ᴄ | When she was four years old, Luna-Katherine got in trouble at her mother's apothecary for playing around with a bottle of herbs. Shocked at being yelled at, she allowed for the herbs to slip out of her hands, and the glass shattered on the floor. The herbs instantly set on fire, for reasons they couldn't explain at the time but that are now attributed to an explosion of magic. Amidst the chaos, Luna-Katherine began to cry, and her tears were found to be acidic, with a pH of 4.7 (almost low enough to cause lasting damage; a pH of 4 or lower is considered a strong acid and would cause lasting damage). As this was a single instance, no damage to her eyes was done; however, she still has a very mild sensitivity to light.
