Arriving via the 'stork' on New Year's day, Jezebel was the prized first child of Stuart (a halfblood ministry worker) and Tanya (a pureblood healer) Blair, though not the birth daughter of Tanya, she was still considered such at the time. Deliriously happy, it didn't take much for the clucky pair to decide to have more children, and Jezebel ended up with three younger brothers and a sister (the triplets being a result of IVF).
However, Jezebel inherited a hereditory gift from birth which wasn't discovered until she was about to begin school and showed signs of erratic behaviour patterns to go with the night terrors that had plagued her on and off since she was a baby. Having taken her to see a specialist straight away, it was discovered after a lot of studying that it wasn't simply behaviour changes, but she actually had developed separate identities in order to deal with various different situations in her sleep. The only solace was that because it had been discovered then she could be counseled and perhaps learn to control herself during her dreaming to an extent, in order to prevent more new 'faces' from being created in her psyche.
And so, life went on, Jezebel's family aware of her and when she seemed to change and gradually getting to know the differences between Jezebel, Jezzie, and Jaz - their likes and dislikes, and general habits. She grew up looking out for her younger siblings like a good older sister, and between her gift and its side effect on her also gained a lot of skill in acting and fooling others. At the age of nine she found herself in a television ad, and from them on began to get the odd spot here and there.
The day she received her letter to attend Magical Academy, it seemed a solid decision that she would go to Penrose like her mother had. This lasted about six months until such a time as Jaz began causing trouble in order to protect Jezebel from the other girls at the Academy who were giving the 'strange girl' a hard time. After a discussion with Jezebel's counselor, and the Headmistress of Penrose and Headmaster of Tallygarunga, they transferred her to Tally where her father had enjoyed his school years, and where she seemed to fit straight in.
A definite change overcame the girl as she found her place and really got into her studies as well as making friends in her House and in a few others as well as a few friendly rivals. She soon found herself comfortable enough to relax and joke around - her first major prank being a combined effort between all her personas to actually convince many students and some staff that she was actually triplets. As she got older only added to her own 'big sister' attitude when it came to younger students - sometimes for the better, sometimes encouraging them in more mischievous ventures. But always looking out for them.
Eventually, as she hit her mid teens, she also shifted from the odd television commercial, to a part time role on a popular soap opera filmed in Melbourne - something which, though enjoyable and paid well and provided great future opportunities, also put a small spotlight on her. She had little interest in being a celebrity (despite now much Jezzie loves it sometimes).
A number of other things happened in her last year of school at Tally, discovering Tanya wasn't her real mother and meeting and falling in love with one Viktor Black being two rather prominent and life changing ones. Jezebel grew and came into her own knowledge of what she wanted to do and pursued it -- eventually being given the offer of a role in Hollywood in a new series, something she definitely couldn't turn down.
Along with that, she discovered her mother's identity and heritage, going through Acceptance, which stabilised her strange power and 'removed' her extra personalities. She spent time learning more about what it means to be the daughter of Adele, and an heir to the throne of L'Arine -- while also trying to work things out with her father's family. Due to wanting to remain close to her families, Jezebel decided to keep her house in Melbourne, and is currently living there most of the time, travelling via floo to Hollywood for work until she decided to take more jobs locally. She and Viktor also came into knowledge of their daughter, who had been taken to L'Arine when Jez thought she had lost their child, so they are now raising Lorelei "Lei" and have formed a happy little family.
Of course, the family has only grown happier and bigger with the arrival of triplets Valerian, Violetta and Veronika around mid 2013, although Jez harbours a secret regarding one of the children, that only she and her mother and Viktor's brother currently know about.
Unfortunately, the happy couple STILL haven't been able to set a solid date for their wedding yet still, even after being engaged for years. There is still much business to be done regarding her mother's family and L'Arindelle. She's beginning to consider the idea of just getting married in secret, though doubts she'd be able to pull it off without someone interfering again, and so has settled for a non-official union for the time being.
