How do you think being a guardian fairy works. Do you get to choose it like any other career? and how do you think it works with princesses (like the winx) or leaders of realms/planets. Love your work!
Hopefully this answers your question and is coherent. ^.^'
Guardian is both a Fairy Level, and a Career Title.
However, while all Titled Guardian Fairies have achieved the Guardian Level, not all fairies who've achieved the Guardian Level, have the Title.
Unlike any other Transformation, the Guardian Level comes with no outward indication of achievement, no new outfit, no new wings; but there is no visible change when a fairy becomes a Guardian, their Magical Perception and Magical Empathy increases dramatically, infusing their magical essence in a unique manner which can be detected by other Guardian Fairies, or by observant magicals.
It is achieved only after extensive training and experience, and so it is rare, but not unheard of, for younger fairies to achieve it.
Much like Enchantix is earned by a moment of understanding what a fairy is willing to sacrifice of themselves for others, Guardianship is earned when a high level fairy undergoes a moment of self-realisation. (“Yes, this is what I'm meant to do, to protect on this grand of a scale, not just the people I love, but all the people and the world(s).”)
Guardianship cannot be lucked into, it takes more than the introspection that earns the Charmix or Enchantix forms, it is a deliberate choice of life long dedication and commitment.
Titled Guardians are typically given the Title by the government/ruling body of their Home World, after receiving nomination by a known Guardian, as most Guardians accept Guardianship of their places of origin. While Titles of Guardianship are acknowledged Dimension over, the exact political power that comes with them changes from planet to planet, with some planets occasionally refusing to acknowledge the authority of a visiting Guardian Fairy if their planets are at odds with each other at the time.
(The exception to this are fairies who are Titled by Alfea, as only students who achieve Guardianship before graduation are Titled by the school, and are therefore considered to be 'neutral' parties. (and unbelievably powerful.))
In addition to protecting the worlds they serve from invasion or attack, Guardian Fairies, Titled or not, are partially responsible for the Magical Stability of their world, which is why there exist a distinction between A Guardian Fairy of a world, and The Guardian Fairy of a world.
(Every world can have several Guardians active at any one time, the exact number depends on the world, and whether or not replacements are available when current Guardians are ready to retire and go from 'active duties' to a more advisory role.)
The (new) Guardian Fairy of a world is chosen when they are young, and long before The (current) Guardian Fairy is ready to retire, this is to ensure that the potential replacement wants to become The (new) Guardian Fairy, and another can be found if they don't.
Unlike other Guardian Fairies, The Guardian Fairy is specifically selected by their power type.
Each world has its own type of magic, its Thematic Magic, like Solaria is the world of Light and the Sun, and Zenith is the world of Technology, The Guardian Fairy will always possess a power that matches or exemplifies the power of their world, like Stella and Tecna.
It is not unusual for a member of the royal family of a world to become The Guardian Fairy, but it is not a certainty. Power Themes tend to be genetic, family lines passing on the same type of thematic power, whether the exact same power, or variations of the same – Stella's (paternal) family line has always produced sun fairies (or on rare occasions, fairies of bright celestial bodies), Bloom's family is filled with fire fairies, (wild fire, hearth fire, fire light) – and the reason many royal families have powers which so closely match the powers of the world, is because the royal lines (Or at least those which are hereditary) were mostly started by what were essentially the first Guardian Fairies.
Guardians who don't receive Titles either become essentially understudies, or second string for Titled Guardians, or find themselves travelling the Magical Dimension, often acting in capacity as bounty hunters tracking down escaped criminals, or monsters that crop up, answering calls for additional aid when a world's Guardians would like a bit of extra help.
UnTitled Guardians who don't remain with their world, often accept the entire Magical Dimension as the area of their Guardianship. (In their later years, these Guardians may settle down on worlds under the understanding that “the whole Dimension is still under my protection, by I am currently in charge of looking after this little corner of it.”)
(Alfean Guardians, those who are Titled by Alfea, act in a similar capacity if they don't have a chosen world, but are also (as acknowledged Guardians) called upon to act as impartial parties during negotiations, and will occasionally put of graduating for several months in order to complete a course on Inter-Galactic Diplomacy.)
All Guardians possess at least their Enchantix, and while it is not an actual requirement for achieving Guardianship, it is an important step to the power level and self-awareness that enables a fairy to reach it.
(While no records exist to modern day, there are several stories of a handful of witches who were said to have achieved Guardian status, whether it is true or not is open to academic debate, with most academics, historians and magi-anthropologists denying the claims under the reasoning that “witches on the whole lack the mindset to choose such a selfless act of life long dedication.”Many witches would like to hex said academics on the grounds “their degrees, doctorates and other such fancies don't teach them $h*t.”)
TLDR:Guardian Fairy is both a fairy level, and a job. It is earned by choice and requires pre-existing high power levels, and dedication to protecting people and planets.Head Guardian in Charge of a planet is often a member of the royal family, and it's just another facet of they run the world to ensure the safety and well being of their people.
Some Guardians look out for the entire Magical Dimension, whether by acting as interstellar bad-asses, or unbiased third party diplomats.
