Over at Goblin Punch, Arnold K. has posted a great article about good fairies, providing a number of different types and statistics for them, along with typical encounters for them. The different types of fairies – Candy, Flower, Gem, and Ice – are all given very detailed write-ups with encounters being treated as sort of negotiated demands where they want something from you before offering anything in return. There are also a small number of specific spells to fairies listed as well.
If you’ve read any of the Dresden Files [AL] novels by Jim Butcher, some of the attitudes expressed by the fairies in the article mirror those exhibited by Toot-Toot and other good fairies that serve in the Summer Court.
A word of warning: the linked article contains a number of pieces of artwork that could be deemed NSFW.
