If we get fairies, it might be a nice idea to have different kinds of fairies with their own specific set of skills. Like there is a tooth fairy (she collects teeth and makes new teeth grow), we could have garden fairies who have skills related to gardens and plants in general, or house fairies with skills related to running a house, or an all purpose mischief fairy who is best at doing mischief. Each one of them would have their own way to appease them, and if you want to befriend them you need to learn things about them, like how to summon them or find them and what they like, and if you want them to help you with something they will send you on errands for them.
That does sound cool, but they don't sound very playable, and I know I'd want to be able to actually play Faeries, not just have Faerie Friends.
They could work like the Spellcasters, and be a sort of teacher from whom you could learn tips and tricks of the fairy folk. Maybe you anger a fairy one day and to spite you they make you a fairy too. Now you are tiny and with no skills, you can't fly and you are clumsy with your new wings, what do you do?
