Are they naughty? Are they kind? Are they mad or noble or both? Are they tiny with buglike wings, or tall with antlers? Do they live in a palace or under the hill or in another world or inside a mushroom? Do they kidnap babies or do they grant wishes? Are they monstrously ugly or enchantingly beutiful?
Maybe they are all of the above.
What are fairies, in your opinion?(Assuming they exist, of course. In most people opinions they are "Not")
Faeries, or Sidhe as they are sometimes known, come in two varieties, or "courts", Summer and Winter, and creatures from basically every mythology ever make up the members of said courts.
Winter is very cold, and brutal. They won't think twice about ripping you apart and bathing in your blood, so long as it brings them an advantage.
Summer is more bright and cheerful. They are much more subtle than their Winter counterparts, but if it's to their advantage, they will kill you just as quick.
Essentially, Winter will stab you in the heart, Summer will get someone else to do it.
However, every word they say is the literal truth, as they are not physically capable of lying. That said, you can't ever trust anything they say, because they have learned how to speak the literal truth, while conveying something completely different. And if one makes a bargain with a Fae, it will invariably involve one getting screwed over. Said bargain will be kept to the letter, but what you expect is never what you get, and the price is always far more than you are willing to pay.
