Mabel was raised in her grandmother's potion shop which was hidden deep within an seemingly endless forest full of large beasts & other dangerous (and sometimes magical) things. A long and bloody war was raging during Mabel's childhood, and as a result her grandmother never allowed Mabel to leave the forest. Since only the strongest and bravest were capable of reaching the potion shop, and most of those folks were busy with the war, they rarely saw visitors.

The young witch filled her days with playing around her grandmother's land and exploring the strange and enchanted things in the forest around her; as she aged, she learned to hunt the more dangerous beasts that lived deep within the trees. Time moves differently deep within the forest, particularly for those raised there; while Mabel is in her late teens, nearly a century has passed in the outside world since she was first left in her granny's care.

Eventually the war outside ended and Mabel was allowed to venture outside her home, though at first she had little reason to as the the meager villages and crumbling cities of the outside world did not interest her. With the changing times Mabel's grandmother started to get more orders and, not wanting her granddaughter to be too spoiled or idle, Mabel would be tasked with flying her broom out of the forest to make deliveries. At first it was only a few times a month, but as the years passed and the world continued to rebuild, her duties became more frequent. Mabel considers her job an annoyance at times, however after seeing how the outside world lives she is aware of how fortunate she is and listens to her granny without complaint.

Mabel has never met her mother and knows little of the woman other than the occasional story she will hear while out in towns making deliveries. From what Mabel can tell, mother is a bit of a “bad witch” that takes jobs to cast curses and destroy lands. Mabel has asked her grandmother a few times about her mother, however granny never has much to say other than “she always was a wild one, that girl.”

During her late teens, Mabel doesn't have much going on her life other than making deliveries for Granny and doing her normal exploring and hunting in the forest. She starts to slack off a bit on her studies as she feels little motivation to further her magic. She already has the all the abilities she needs for her day to day life and Granny isn't going any where any time soon so she doesn't see much of a reason to be pushing herself. She does put more effort into improving her flying abilities, as she notices when she approaches towns people will often stop to watch her, and she wants to be sure she looks good when she lands and never flies into anything.

As Mabel journeys more, she starts to feel more of an attachment to the outside world. While she never really makes any friends, she does take note of certain places and people, and she'll often check up on them whenever she's in the area. She comes to view her favorites as “her people” and sometimes will cast spells to try and help them, though it often doesn't work out how she hopes. Having grown up in the magical world completely cut off from normal humans, Mabel had always looked down non-magical people, and while she does grow to have more empathy for them, she still maintains a bad habit of viewing them more as things to be observed and sometimes tampered with.

When Mabel first starts her delivery service, Granny only tasks her with going to small villages and towns. As the years pass, she begins flying to bigger cities and delivering to more wealthy and important figures. Eventually, Granny entrusts Mabel with making deliveries to the nobles in the country's capital. At first Mabel is intrigued to be going to the capital, but it quickly disappoints. She finds the way the poor people live in dirty, over crowded places sad, and the way the rich live in gaudy homes following all sort of strange high-society customs ridiculous. And everyone is rude.

One day when making a delivery to the capital, Mabel takes a detour to fly over the royal family's castle. While high in the air on her broom, she is shot out of the sky by several arrows. While the arrows do not hurt her physically, she does crash land into a tree and her pride is badly injured. One of the arrows ends up stuck in her capelet, and as she looks it over the arrow fades into a strange shadowy substance then vanishes. At this point she realizes they were shot by a magic user, causing her to go from displeased to insulted. Mabel had not realized anyone around the humans could use magic (because she had never bothered to learn about humans, or she'd have know the royal family has soldiers with magic) and she could not believe one of them would shoot at her.

With this new information, Mabel begins a new quest: find who shot that arrow, and get revenge on them.
