The godmother class is the highest kind of fairy and it is from them recruits for the angels are usually found when godmothers reach the end of their time in the Fairy Kingdom. Fairies like Hanastrew are not yet godmothers but are clearly going to get there.
Those like the fairy squad will be the working fairies, some of whom will gain promotion, some of whom will stay put. Not every fairy wants to be a godmother - a great deal more responsibility comes with it. Fresdian (Rose)managed to disguise her true godmother class to avoid those responsibilities.
All fairies practice their skills regularly. Most fight like demons too when called on to do so by the Kingdom.
Fairies are the top species in the realm, mainly due to their powers and the way the royals tamed the Kingdom and stopped the infighting, though it took them centuries to do it. Most of the Kingdom doesn’t have a problem with this though every so often a disgruntled wizard or witch rebels and shakes the Kingdom throne up somewhat.
The fairies act honourably and don’t throw their weight around though there is always the odd exception. Hanastrew and the squad generally go down well with the populace given they’re the first line of magical defence.
Fairies tend to despise humanity’s view of them - they are not twee, yes they like flowers but don’t necessarily live in them and the ones that do are considered suspect by their own kind. Fairies are tough, good fighters and love nothing better then righting injustices. They very much see themselves as the good guys of the magical world.
