What did you think I meant?
All the things!
( especially the sexual ones )
Fairies need love too! Large, throbbing, injections of love!
Besides, having a few pregnant fairies around can't be a bad thing. It would make the elf-haters really go mad. =D not only 1 fantasy race, but another they didn't even know existed! and they can reproduce together too?? waaaa!
(this requires further investigation... )
Maybe this could be where mages come from, - perhaps if humans or elves have a fairy heritage mixed into their family tree, they might have an affinity for casting and using magical spells. hmmm..... That could lead to some interesting future storylines where technology and magic both exist regularly in the world.
It could lead into a game where the main character is a mage descended from a union between the current main character and one of the fairies.
