The Fae (or fey) are strange beings that don't seem to exist entirely in the physical world. This unseated nature allows them to do things that are impossible for mundane creatures.
The fae "economy" is built on debts and favors.
Peonies, daisies, holly, morning glory, and forget-me-nots are symbols of a promise of protection from a fey queen. see http://www.rhjunior.com/totq/00494.html
The fae cannot bear to be near lode-iron
The fey are easily distracted by puzzles, riddles, and challenges.
A fey who grants a boon is expected to use every resource at his command to fulfill it.
Also called brownies, gnomes use what little lux power they possess for jumping
Bogeys (or bogies) are shapeshifters who extort treats and shineys from children and kits by scaring them in groteque shapes. Bogeys are not known for loyalty.
Dryads are small fey that live inside trees, tending to them and keeping them healthy in exchange for food (bark, sap, fruit, seeds). They're called a 'boon to the orchard, bane to the lumberyard.'
The queens, at least, are intelligent enough to barter with.
Spriggans are a lot tougher than Bogeys.
Grindylow - beshadowed so you couldn't see it with plainsight.
